(Luke 22:32- 34- but I have pleaded in prayer for you that your faith should not completely fail. So when you have repented and turned to me again, strengthen and build up the faith of your brothers. ”Simon said, “Lord, I am ready to go to jail with you, and even to die with you.” But Jesus said, “Peter, let me tell you something. Between now and tomorrow morning when the rooster crows, you will deny me three times, declaring that you don’t even know me.”) In this same chapter Jesus is arrested and as Peter follows Jesus at a distance people begin to recognize him. Every time someone claims that he knows Jesus he denies it. (Luke 22:61-62- At that moment Jesus turned and looked at Peter. Then Peter remembered what He had said—“Before the rooster crows tomorrow morning, you will deny me three times.” And Peter walked out of the courtyard, crying bitterly.)
Peter could’ve remained bitter but he repented and turned back to Jesus. He wrote 1 Peter 1 and 1 Peter 2 and strengthened the faith of his brothers just like Jesus said. (1 Peter 1:6-7- So be truly glad! There is wonderful joy ahead, even though the going is rough for a while down here. These trials are only to test your faith, to see whether or not it is strong and pure. It is being tested as fire tests gold and purifies it—and your faith is far more precious to God than mere gold; so if your faith remains strong after being tried in the test tube of fiery trials, it will bring you much praise and glory and honor on the day of his return.) Peter knew that the going was rough down here because of what he experienced and used what he learned to help his brothers. He learned, grew and encouraged others from his mistakes.
(1 John 1:9- But if we confess our sins to Him, He can be depended on to forgive us and to cleanse us from every wrong. And it is perfectly proper for God to do this for us because Christ died to wash away our sins.) God wants us to admit that we’ve messed up but He also wants us to learn from it. David was also a man who learned from his mistakes. When David slept with Bathsheba, they had a son but he died because of their sin. David could’ve allowed his son’s death to cause him to be resentful but he did the unexpected. (2 Samuel 12:20- Then David got up off the ground, washed himself, brushed his hair, changed his clothes, and went into the Tabernacle and worshiped the Lord. Then he returned to the palace and ate. ) I’m sure that David was dealing with many emotions because of his son’s death but he knew that in God’s presence there is the fullness of joy. Instead of getting bitter he got better.
The Bible is full of people who made mistakes. Sometimes when you mess up it feels like it’s the end of the world but I want you to know that it’s not. Just like there was grace for Peter and David, there is grace for you. Instead of getting bitter, get better. Know that you serve a God who is merciful and just wants you to repent and turn back to Him when you mess up.
