Acts 13:2 says 'As they ministered to the Lord and fasted, the Holy Spirit said, "Now separate to Me Barnabas and Saul for the work to which I have called them." Consecrate means to devote or dedicate to some purpose; to make or declare sacred; to set apart or dedicate to the service of God. Here we see that Barnabas and Saul were being set apart or consecrated by the Holy Spirit to do a specific work for the Lord. Each one of us are called to be ministers of reconciliation, which means to tell others about what God has done for you. To be a witness. Once we have accepted Jesus as our savior, our lives should reflect the dedication we have made to the Lord by our confessing that Jesus Christ is Lord. Our lives will be lived and will show exactly what we believe. Are we devoted to God? Do we live in such a way that we are known as Christians, or are we not seen as separated from the way the world does things? Can the difference be seen between us and the world? 2 Corinthians 6:14-18 (TPT) says 'Don't continue to team up with unbelievers in mismatched alliances, for what partnership is there between righteousness and rebellion? Who could mingle light with darkness? What harmony can there be between Christ and Satan? Or what does a believer have in common with an unbeliever? What friendship does God's temple have with demons? For indeed, we are the temple of the living God, just as God has said: I will make my home in them and walk among them. I will be their God, and they will be my people. For this reason, "Come out from among them and be separated," says the Lord. "Touch nothing that is unclean, and I will embrace you. I will be a Father to you, and you will be my beloved sons and daughters," says the Lord Yahweh Almighty.' Be consecrated unto God. The Lord has dedicated Himself to us. We need to be His just as much as He is ours.
