It is only by the Resurrection of Christ, that believers enter into the newness of life and gain eternal life. Eternal life is not a future event of life for us, it is now because the Kingdom of God is now and within us.
We must partner with our identity in Christ, rather than the identity of our own strength or what dead religion will tell us!
Romans 8:11(NKJV) But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ from the dead will also give life to your mortal bodies through His Spirit who dwells in you.
