What God did for His people, Israel, was very great. There is a striking contrast between their slavery in Egypt and their abundance in the promised land. God had multiplied His blessing upon them, just as Jesus did when He turned water into wine (John 2:1-11). If the blessing is to be maintained and increased, we must honour the Lord. We must cry to Him for blessing: “Hear my prayer, O God, listen to the words of my mouth.” We must call upon Him with faith: “Surely God is my help; the Lord is the One who sustains me” (Psalm 54:2,4).
In all the social details of the division of the land, we must not lose sight of its spiritual basis (Joshua 21:43-45). The important thing is that God, and not man, receives the glory: “Do not rebel against the Lord or against us by building an altar for yourselves, other than the altar of the Lord your God” (Joshua 22:19). If God, and not man, is to be exalted, there must be new birth (John 3:3,5-7). To the man who is obsessed with his own problems – “My heart is in anguish within me …” (Psalm 55:4-5), God gives us “the wings of a dove” (Psalm 55:6) – to rise to higher things.
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).
