Paul says in 2 Corinthians 2:14, "Thanks be to God Who leads us always in His triumph". The Living Bible paraphrases that as, "Thanks be to God! For through what Christ has done, He has triumphed over us". So God must triumph over us in every area of our lives, for us to live in triumph.
One day every knee will bow and acknowledge that Jesus is Lord (Phil.2:10, 11). But right now, the knee of every desire within your flesh must bow and acknowledge that Jesus is Lord. Those lusts that rule you must bow and acknowledge that Jesus is Lord of your body.
"The Lord's sword will go forth against all flesh from head (north) to foot (south) and all flesh will know that the Lord has drawn forth His sword against it" (Ezek.21:4,5).
The goal towards which God is working is that "Jesus Christ might have the first place in everything" (Col.1:18). If you make that your goal too, then you can count on receiving God's help at all times - both in your life and in your witnessing for Him.
Christ must have first place in the way you spend your time and your money, in the books you read, in the music you listen to, in the TV programs you watch, in the friends you keep company with, in your speech, in everything. This is what it means to make Jesus Lord of all. Only then can you say that God has triumphed over you in every area. This is not something that can happen overnight. But make this your long-term goal, and keep working toward it. Then you will draw nearer and nearer to that goal day by day, and year by year.
Jesus was the Lamb of God Who bore the sins of the world. We are now called to be "sheep for the slaughter (Rom.8:36), bearing with the sins that others commit against us. The wood and the fire (the circumstances of our life) are all ready, as on Mount Moriah. But the question (like Isaac asked his father) is, "Where is the lamb" (Gen.22:7)? The answer is "You are to be the lamb".
