"And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it." - Matthew 16:18 (NIV)
In this verse Jesus chooses Peter as the rock on which to build His church. But we also see throughout scripture that Peter had several weaknesses. He often spoke before he thought the situation through. He was impulsive, abrupt in his actions, and discourteous to those around him. Peter was the disciple that cut off the ear of the high priest's guard as Jesus was being arrested in the Garden of Gethsemane.
Peter said he would die before disowning Jesus, but as Jesus predicted he would deny Jesus three times before the crucifixion. Jesus was aware of Peter's shortcomings and failures, yet He saw Peter's true heart. He knew Peter would go on to do great things for God's kingdom.
Just like Peter, we have many shortcomings and frequently fail at our endeavors. However, when this happens we must never think that God can't use us. Through God's strength and power, we can achieve all that we are called to do.
Dear Lord, help me to remember that I can rely on Your strength to accomplish what You call me to do. In the name of our Lord and Savior, Amen.
