Another change in Peter's life was that he was deeply inquisitive but after Pentecost, he was very submissive. Some times there are things that we don't understand and are not for us to know and we need to be very submissive to Christ and learn from him in humility.
John 21:21,22 "Peter seeing him, said to Jesus, 'But Lord what about this man? Jesus said to him, 'If I will that he remain till I come, what is that to you?" Jesus was telling Peter what was going to be his end and he wanted to know what the end of John was going to be, but it wasn't for him to know John's ending. Sometimes we want to know something which is not for our best good, especially our future. It is best if we just live from day to day and not worry about our future ending or anyone else's. It would probably just be something else for us to worry about. If we put our lives in the hands of God, there shouldn't be any worries.
In Acts 11:2-17 it tells the story about Peter going to the Gentiles and eating with them. Before their conversion they believed that they were better than the Gentiles and shouldn't associate with them but God showed Peter through a vision that it was OK for him to go to the Gentiles and convert them also. You can read these verses and see the story. Peter became submissive to God and went and preached to the Gentiles. From wanting to know everything, after Pentecost he became submissive to God's orders and not ask questions.
Wouldn't it be wonderful if we became so submissive to God that there would be no questions to ask as to what is going to happen to us? If the Holy Spirit will do that for Peter, what can He do for us who are living in this end time, just before Jesus comes. We need His Spirit more than ever before, to be strong for the Lord and submissive to Him to do His will and not our own. If God could change Peter, He can change us to be submissive, enlightened, humble and courageous. What do you think? I believe He can and He will if we are willing and make that choice. Are you willing? I am. Grandma Joan
