He has delivered us from the power of darkness and conveyed us into the kingdom of the Son of His love (Colossians 1:13, NKJV).
It is essential we correctly identify “the kingdom of the Son” into which God transfers the lost when saved (delivered out of sin’s powerful darkness). Jesus said His kingdom is not of this world (John 18:36). While He was on the earth, He withdrew from those who wanted to make Him king forcibly (John 6:15). The nature of His kingdom is spiritual. Therefore, it is established or advanced by earthly means (Luke 17:20-21). Premillennialists teach Jesus will conquer evil and return to earth to reign over a thousand-year kingdom. But, the saved ones are already fellow citizens of His kingdom (Col. 1:13; Rev. 1:6, 9). Jesus identified His kingdom as His church in Matthew 16:18-19. Jesus now reigns as the victorious king over His kingdom, the church (Psalm 2; 110:1-2; Acts 2:32-36; Heb. 1:8-9, 13). Christ has secured victory over sin and death. His church triumphs over sin and Satan by the blood of the Lamb, who is worthy to reign (Rev. 1:5-6; 5:9-10, 13). Thus, Scripture says we are “receiving a kingdom” (receiving is a present, active participle) now (Heb. 12:28). The church of Christ is the kingdom of Christ. Christians currently serve the King “in the day of His power” (Psalm 110:3; Matt. 28:18; Eph. 1:20-23; Heb. 1:3). The saved compose Christ’s kingdom, His church (Acts 2:47). The church is the kingdom that cannot be shaken by the kingdoms of men (Dan. 2:44; Heb. 12:28). God be thanked Jesus reigns today as “the Lord of righteousness” (Jer. 23:5-6; Heb. 1:8-9).
