1 Then He called His twelve disciples together and gave them power and authority over all demons, and to cure diseases. 2 He sent them to preach the kingdom of God and to heal the sick. (Luke 9:1–2, NKJV)
Jesus gave His apostles power (capacity) and authority (the freedom to act) over demons and diseases. He sent them to preach the kingdom of God and to work miracles which confirmed the divine nature of their message. The New Testament identifies the kingdom of God as the church of Christ (Matthew 16:18-19; Colossians 1:13). Preaching the kingdom of God is central to preaching Christ. When the evangelist Philip preached Christ, he preached “things concerning the kingdom of God” (Acts 8:5, 12). We fail to preach Christ if our preaching minimizes His church (His kingdom). There is rich irony in one thinking he can preach Christ to sinners (so they can be saved and added to the church, His kingdom, Acts 2:47) by not preaching the church (the kingdom) to them! Such is the feeble and futile attempt to preach Christ but not His church. We cannot preach Christ (the Anointed One, the King) without preaching His kingdom, His church. Truly, the gospel of Christ is the gospel of the kingdom (Luke 4:18, 43-44). Jesus preached the gospel of the kingdom, and so did His apostles. When early Christians preached Christ, they preached His kingdom (the church). When we preach Christ, we must preach His kingdom, His church.
