Hebrews 6:1-2

Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God, Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment.

This is the basic gospel of Christ. This is what we have to do to follow Christ. We must first believe and ask for forgiveness with the faith that Christ will do so. Our second action is the act of baptism and conformation into the Church. Thirdly we wait for the resurrection and eternal life with Christ. We must complete all the steps and we must do them in order.
