The concluding message, preached by Joshua, is a call for the people to exalt the Lord. They make a definite and public commitment to the Lord. The Christ-centredness of real commitment to the Lord is summed up in the words of John the Baptist: “He must become greater; I must become less” (John 3:30). We must confess Christ and honour Him – “The One who comes from heaven is above all” (John 3:31). We must listen to what He says to us – “The One whom God has sent speaks the words of God, for God gives the Spirit without limit” (John 3:34). It will not be easy to live a life of true commitment to Christ. Nevertheless, we have God’s promise: “Cast your cares on the Lord and He will sustain you” (Psalm 55:22).
