So, what was the difference between Judas and Peter? After all, Judas betrayed Jesus and then Peter fell into the same type of mess as Jesus told him he would:
And when they had sung a hymn, they went out to the Mount of Olives. And Jesus said to them, “You will all fall away, for it is written, ‘I will strike the shepherd, and the sheep will be scattered.’ But after I am raised up, I will go before you to Galilee.” Peter said to him, “Even though they all fall away, I will not.” And Jesus said to him, “Truly, I tell you, this very night, before the rooster crows twice, you will deny me three times.” But he said emphatically, “If I must die with you, I will not deny you.” And they all said the same. (Mark 14:26-31 ESV)
The point is this. We are imperfect. We all make mistakes. Our church signs should say ‘No Perfect People Allowed’. Yet, Judas fell away and never returned…as a matter of fact it appears that he was never more than partially committed. Whereas Peter fell away, repented and returned. That is the process for us as imperfect people. Note the encounter at the end of John 21 where Jesus restores Peter. What grace! What forgiveness. Guess what - you can receive that same empowering grace from that same Jesus. Not perfect - He was so you can rely on His perfection. Messed up - repent of your sin and rest in His Grace. Knocked down - all Him to lift you back up again and get going on this journey of following Jesus where you live, work and play!
Being permanently committed doesn’t mean perfection from you it means applying Jesus’ perfection to you so you can run and not faint in your service to Him.
