Impetuous Peter often put his foot in his mouth or reacted too quickly and immediately had to face the consequences.
Matt 16:21 23 From that time on Jesus began to explain to his disciples that he must go to Jerusalem and suffer many things at the hands of the elders, chief priests and teachers of the law, and that he must be killed and on the third day be raised to life. Peter took him aside and began to rebuke him. "Never, Lord!" he said. "This shall never happen to you!" Jesus turned and said to Peter, "Get behind me, Satan! You are a stumbling block to me; you do not have in mind the things of God, but the things of men."
1 John 18:10,11 Then Simon Peter, who had a sword, drew it and struck the high priest's servant, cutting off his right ear. (The servant's name was Malchus.) Jesus commanded Peter, "Put your sword away! Shall I not drink the cup the Father has given me?"
Mattt 14:28-31 "Lord, if it's you," Peter replied, "tell me to come to you on the water." "Come," he said. Then Peter got down out of the boat, walked on the water and came toward Jesus. But when he saw the wind, he was afraid and, beginning to sink, cried out, "Lord, save me!" Immediately Jesus reached out his hand and caught him. "You of little faith," he said, "Why did you doubt?"
Consider your actions and replies, develop a Christ-like attitude and lifestyle and the kindness and thoughtfulness will have you automatically react in the way that will bring good consequences and blessings rather than getting yourself in hot water with impetuous reactions.
Titus 2:7,8 In everything set them an example by doing what is good. In your teaching show integrity, seriousness and soundness of speech that cannot be condemned, so that those who oppose you may be ashamed because they have nothing bad to say about us.
Think on Jesus' words:
John 14:23,24 Jesus replied, "If anyone loves me, he will obey my teaching. My Father will love him, and we will come to him and make our home with him. He who does not love me will not obey my teaching. These words you hear are not my own; they belong to the Father who sent me.
