When Jesus chose his disciples, He seemed to know all about them, their characters and personalities; the good qualities as well as the not so good. But more importantly, Jesus knew their potential, what they would become under His teaching and guidance.
Take the disciple, Simon. Jesus said to him, “Your name is Simon, son of John but you WILL be called Cephas which means Peter, the Rock.” Notice the tense. Jesus was pointing to a time in the future. Later on, after Simon had declared that Jesus was the Messiah, He said to Simon, “Now I say to you, you ARE Peter, the rock.”
Over time, Peter changed in his understanding of who Jesus was. Even so, Peter had some way to go. After Jesus had been arrested and placed on trial, Peter denied that he ever knew Him three times. But Jesus did not write Peter off as a lost cause. After Jesus’ resurrection, He held a breakfast meeting and Peter was restored and commissioned by Jesus to go and feed His flock.
At Pentecost, Peter, filled with the Holy Spirit, preached boldly to the crowds and about three thousand believed in one day. Peter had reached his potential, that which Jesus had seen when He first set eyes on him years before.
When Jesus calls us to follow Him, He knows our potential too. So, let us walk with Jesus and learn from Him each and every day so that we reach the potential that Jesus first saw in us and bring glory to our Heavenly Father.
