You, however, are not in the realm of the flesh but are in the realm of the Spirit, if indeed the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, they do not belong to Christ. Romans 8:9
If you truly are a Christian then the Holy Spirit lives in you. The same Spirit that raised Jesus Christ from the dead, is the same powerful Spirit that lives in you. God said he won’t leave us or forsake and he doesn’t thru the power of the Holy Spirit.
But if Christ is in you, then even though your body is subject to death because of sin, the Spirit gives life because of righteousness. Romans 8:10
Make no mistake about it, you are still mortal due to the sin of Adam. The time will come when your body will fail you, however because of the redemption of Jesus, you will be risen from the dead just as Jesus was.
And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies because of his Spirit who lives in you. Romans 8:11
The Spirit of God is living in you and will give you eternal life thru the atonement of Jesus Christ. Jesus defeated death on the cross and crushed the head of the serpent. The grave can hold you no longer.
However to receive the power of the Holy Spirit, you must accept and confess Jesus as your Lord and Savior. You must also confess and repent your sins, for we are all sinners and have fallen short to the Glory of God.
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life John 3:16
Whoever believes in him should not perish, I promise from God your creator. Everlasting life can be yours, follow Jesus he is the truth, the light, and the way Amen
