1 Corinthians 4:20

For the kingdom of God is not in word, but in power.

Kingdom of God. Here the kingdom of grace as in Col. 4:11; etc. (see on Matt. 3:2; 4:17; 5:3).

Not in word. God’s spiritual kingdom on earth is not established or administered by boastful claims and the vain words of men. Something more is required than confident assertions of authority by those who, not willing to abide by the simplicity of the gospel message, add to it their own interpretations of truth and exalt themselves to positions of leadership and authority (see Dan. 7:25; 11:36; 2 Thess. 2:3, 4; Rev. 13:5, 6).

Power. Gr. dunamis, “force,” “might,” “strength.” Our English word “dynamite” is derived from dunamis. The church of God is sustained by the power of the Holy Spirit, operating in the lives of wholly consecrated believers. Every addition to the church of God is brought about by the regenerating power of the Holy Spirit (see John 3:5; 16:13). The leaders of the church are guided by the Spirit of God and empowered by Him for the wise administration of His kingdom on earth (see Acts 1:8; 2:17, 18; 13:1-4).
