From the sermon preached on September 13, 2026
"I am Almighty God; walk before Me and be blameless." God spoke those words to Abram after 24 years of waiting, and they show how He meets spiritual exhaustion. He renews tired faith by drawing us back into His presence and rehearsing God's promises to a humble heart.
In a message from Genesis 17, Barry Mershon, Lead Pastor of Believers' Chapel, began with an honest guess about the room. You are probably tired, and you are probably stressed. Even on a good morning, concerns, fears, and unanswered questions can quietly wear a person down.
Abram and Sarai knew that weariness. In Genesis 16 they tried to help God along in their own strength, and the result was Ishmael rather than the promised son. Spiritual exhaustion often grows out of exactly that kind of well-meant self-effort.
Genesis 17 shows three ways God renews weary people. He calls us to live before Him as chosen and loved, He looks for hearts rather than habits, and He keeps His word on His own timetable.
What Does Walking With God Look Like When You Feel Worn Out?
God's first word to a weary Abram was an invitation to His presence. "Walk before Me" was a call to make God the focus of Abram's life instead of performing for everyone else. Walking with God begins with believing that He is present, active, and engaged in the good, the bad, and the ugly of your life.
Being blameless does not mean being perfect; it means living before God in obedience. Later in the chapter, Abraham pleads, "Oh, that Ishmael might live before You!" Barry Mershon explained that to live before God meant living as the chosen one, the son through whom God's blessing would pass to future generations.
The New Testament gives every believer in Jesus Christ that same footing. The apostle Paul describes believers "as the elect of God, holy and beloved," so walking with God starts from His love rather than from an effort to earn it. We walk because we are already chosen.
Barry admitted that when he is tired, he forgets this truth. He still knows the information, but it stops moving his heart, so he returns to a book by author Neil Anderson on our identity in Christ and lets lines like "I am loved by God" soak in. Then he prays the plainest prayer there is and tells God he needs renewal.
Abram's posture is worth copying: "Then Abram fell on his face, and God talked with him." A humble heart is a good place to listen. Today, find a quiet minute, read Colossians 3:12 out loud, and tell God honestly that you need Him to renew you.
Why Real Faith Renewal Starts in the Heart, Not the Ritual
After rehearsing His promises, God gave Abraham the sign of circumcision. It belonged to the whole community and was meant to carry across generations. An eight-day-old boy did not walk there himself; mothers and fathers brought their sons because they wanted the blessing of Abraham to flow into their children's lives.
Over time, the act became the point and the heart was set aside. Centuries later, some Jewish believers insisted that Gentiles be circumcised to be saved, and the first church council in Acts 15 stood firm on the grace of God alone. Paul had already named the deeper purpose: "circumcision is that of the heart, in the Spirit, not in the letter; whose praise is not from men but from God."
Faith renewal does not come from repeating a ritual harder. Barry Mershon warned that the flesh will exalt the act and ignore the heart, and the same thing can happen with the practices God gives the church today. Believer's baptism by immersion pictures new life in the Father, Son, and Holy Spirit, and the Lord's Supper remembers what Jesus called "the new covenant in My blood," yet a person can go through both with a cold heart.
Paul describes the new self as "renewed in knowledge according to the image of Him who created him." The Greek word for knowledge there, epignosis, means a relational knowing that grows as you walk with God, rather than a stack of collected facts. That is where faith renewal lives, because Christ is all and in all.
Faith renewal begins when we want the reality behind the sign. Before you open your Bible or pray tomorrow, pause and ask the Holy Spirit to renew your love for Jesus as well as your routine.
How Waiting on God's Promises Builds a Faith That Lasts
Moses keeps quietly marking time in Abram's story. Abram was 75 when he left Haran, 86 when Ishmael was born, and 99 when God appeared in Genesis 17, which adds up to 24 years of waiting on God's promises with no son from Sarai. Barry Mershon called time an essential part of discipleship that rarely gets talked about.
Years ago, Barry, his dad, and a couple of friends worked the chain gang at Riverdale High School football games in Murfreesboro. They stood on the visitors' sideline, where opponents ran out fired up and ready to win. Riverdale's skill and consistency wore those teams down, and by halftime or the third quarter the visiting sideline was usually very quiet.
Our flesh starts strong and fades the same way, which is why spiritual exhaustion so often shows up around halftime. Barry compared it to taking sermon notes and forgetting them by lunch, versus memorizing one verse and living with it from Monday through Saturday, or for a whole month. When Jesus said, "Abide in Me, and I in you," He was calling us to remain with Him for a lifetime.
Waiting on God's promises is hard because the flesh does not like to wait. Even so, God came with grace for Sarai, who had helped make the mess in Genesis 16, and promised, "I will bless her and also give you a son by her." Then He set the date, saying Isaac would be born "at this set time next year."
Abraham obeyed immediately, circumcising every male in his house "that very same day, as God had said to him." Waiting on God's promises looks like steady, prompt obedience while God does His work. This week, choose one verse from Genesis 17, write it down, and come back to it every day through Saturday.
What Genesis 17 Shows Us About Being Renewed by God
Renewal in Genesis 17:1 begins with God rather than with Abram. The chapter falls into three parts, each opening with God's own words, and together they show how God's promises meet a tired heart.
1. As for Me
What God Says: "As for Me, behold, My covenant is with you, and you shall be a father of many nations."
What It Means for You: God commits Himself first, and renewal starts when you hear His promises again with a humble heart.
2. As for You
What God Says: "As for you, you shall keep My covenant, you and your descendants after you throughout their generations.”
What It Means for You: Faith is lived in community and handed from parents to children.
3. As for Sarah
What God Says: "As for Sarai your wife, you shall not call her name Sarai, but Sarah shall be her name."
What It Means for You: God's grace reaches people who have made a mess, and that grace renews weary hearts.
Barry Mershon also named the warning signs that the flesh (our own human strength and wisdom) has taken over.
Discontentment that keeps creeping in
Fears that begin to preoccupy the heart
Thinking that is no longer quite accurate
Anxiety that settles in and stays
A tired urge to quit by halftime
You Do Not Have to Carry Tired Faith Alone
Spiritual exhaustion is heavy, and it can make good habits feel hollow and old promises feel forgotten. For Abraham, God's answer was His presence, a humble heart, and a people to belong to, and He still renews His children the same way. Whether you live in Murfreesboro or anywhere else across Rutherford County and Middle Tennessee, Believers' Chapel gathers on South Rutherford Boulevard across from Black Fox Elementary, with jeans welcome and fresh coffee on.
Come Back to the God Who Keeps His Promises
Genesis 17 shows a weary 99-year-old man being met by Almighty God, reminded of God's promises, and called to walk before Him from the heart. Renewal comes from returning to the One who loves us and keeps His word, and the flesh cannot produce it. As Barry Mershon put it, Christ is our focus: He is the One who gave us new life, who loves us, and who renews us.

-
Start where God started with Abram: come into His presence humbly and hear His promises again. Remind yourself that in Christ you are chosen, holy, and loved, and honestly ask the Holy Spirit to renew your heart. Stay with one passage over days and weeks rather than reaching for a quick fix.
-

-
El Shaddai is translated "Almighty God" in Genesis 17:1. With Abraham, Isaac, and Jacob, God often used this name when speaking about descendants and His promises to them. It reminded Abraham that the God who promised a son was fully able to deliver.
-
God renamed Abram "Abraham" because He had made him "a father of many nations." He renamed Sarai "Sarah" and promised to bless her with a son, showing grace even after her mistakes in Genesis 16. The new names rehearsed God's promises before Isaac was born.
