If you are a child of God, you are so because of God’s advance activity. That advance activity predates any awareness of your own of His interest in you or His love for you. But at a moment in time, you experienced Him calling you—you heard Him speaking to your heart. This passage also assumes a response for it says that something else happened in that moment.
What moment is that? It is that moment in eternity past when God foreknew every action and inaction—every response and every rejection—when by God’s advance planning decisions were made and actions were taken—plans formed long ago in perfect faithfulness—and secured and established so completely that nothing can alter His purpose. Our pastor uses one incident in the life of Peter to give a practical illustration of these great truths. This message gives the secret to what guarnteed the outcome of events in Peter's life and ours!
