It is always about what God has done for you, not what you are doing for God. No one can do what Jesus did; no one can do what God is waiting to do in you through Christ by the Holy Spirit. What people “do” for God is often trying to do what God has already done for all through Jesus.
There is only one Holy One. There is only one Righteous One. There is only one Messiah. There is only one Christ of God, the Creator of heaven and earth. There is only one Son of God, the exact image and likeness of God, who came as Son of Man, the Last Adam, so we can come to Christ through the finished work of the Cross and enter into intimate relationship with glorified Christ to be one with God our Father, as Christ is perfectly one with our Father.
Jesus as Son of Man, the last Adam, said on the Cross, “It is finished!” It is only finished in you when you accept his grace, acknowledge what he has done for you, and die with Jesus through your free will choice: let the perishable seed of fallen Adam, that grows satan’s tree of the knowledge of good and evil within you, die with Jesus.
Resurrected, Ascended, Glorified Christ Jesus is the imperishable seed, that when received into your heart grows the Vine of Christ in you, a tree of life, connecting heaven and earth in Christ. The Holy Spirit and fire River of glory sent out of heaven from God, waters the tree to bear Christ Fruit of Righteousness that remains so you can hear and say with Glorified Christ, “Come, take the Water of Life without price.” Hear and do the Word and Spirit of God. “Behold, I make all things new!”
If any one is in Christ they are a new creature, the two become one, in the new covenant; the former things of Adam are passed away; behold, the new of Christ in you has come. Only the Holy Spirit can do the work of God in you.
