The starting point of every Believer is the cross of Christ. The cross is on hundreds of thousands of churches. Most people have several crosses in their homes on the wall or in picture form. This is the starting point of a Believer's life in Christ; but there is so much more.
Like the blood on the doorposts for the Children of Egypt, the blood of the Lamb of God cleanses us of sin and removed the iniquity from our home. The destroying angel passes us by. But Jesus is so much more than the Lamb of God for us now; He is the risen LORD who baptizes in the Holy Spirit.
We have the self same Spirit of the Risen Christ dwelling in our being. The Spirit that brought life to the lifeless body of Christ in the tomb is in us. The Spirit of the One who now sits at the right hand of the Father raised Jesus, the One who went down in death but is alive right now in glory!
He is a man, and God, interceding for us and making His Holy Spirit available for all Believers. He has taken up His dwelling place in us also and although in the bodily nature we inhabit may die if the Rapture is delayed, by the virtue of His Spirit in us we shall never die; He never leaves us. This body will again be quickened because of this same Spirit.
Romans 8 says that we are not in this flesh but in the Spirit; if the Spirit of Him (God) who raised up Jesus from the dead dwell in you, He that raised up Christ from the dead shall also quicken your mortal bodies by His Spirit that dwells in you."
We are truly a new creation in Christ! We have a different Spirit than the world. Take it by faith and build on it. Appropriate the whole concept into our actions, our prayer life and our faith.
II Corinthians 5:17
"Therefore if any man be in Christ he is a new creature;
old things are passed away,
behold ALL things are become new!
