"Then he said to them all: “Whoever wants to be my disciple must deny themselves and take up their cross daily and follow me. For whoever wants to save their life will lose it, but whoever loses their life for me will save it. What good is it for someone to gain the whole world, and yet lose or forfeit their very self? Whoever is ashamed of me and my words, the Son of Man will be ashamed of them when he comes in his glory and in the glory of the Father and of the holy angels." Luke 9:23-26
Once you have seen Jesus and understand Who He is, you can never be the same! Peter's confession of Christ shaped his life forever! It was his defining moment.
How did it define his life?
First, it defined His meaning.
Peter was a fisherman become follower. Jesus had promised him He would become a "fisher of men". But had that happened yet? No really. So, what value is there in being a non-fishing fisherman? Not much.
Fully knowing Who Jesus was meant that Peter now would fish differently with different bait, a new hook and a bigger net!
His new bait? JESUS!
His new hook? LOVE!
His new net? THE GOSPEL OF JESUS CHRIST!
Second, it defined his mission.
When Peter first decided to follow Jesus he left his nets and his boat to learn about this amazing new Rabbi. He became a follower because of what it could do for him and if it did not work he could always go back to fishing. Peter had a fall back position - a "plan B".
His confession of Jesus would change that forever!
Once you truly understand Who Jesus is and confess Him as Savior and Lord, there is no more "plan B". Either you are all in or you are out! Peter understood that. His mission was to be fully committed to making Christ known to others. The news was too good to keep! Evangelizing became His purpose and His top priority.
Committing to Christ marks the end of casual, aimless living!
How did he do? Read the first several chapters of Acts!
Third, it defined his message.
When you know Who Jesus is, how can you stay silent about it? When you have witnessed miracles and seen people delivered and the dead raised, how can you not tell others about that? You can't! You must!
Others needed to hear it and Peter needed to tell.
How did he do? Read the first few chapters of Acts!
Once you understand Who Christ is and once you confess Him it should dramatically and fundamentally change you! It should change your meaning - has it? It should change your mission - has it? And it should change your message - what are you talking about?
