The good gift that God gives us is the Holy Spirit
Amen. "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 through His Spirit, who lives in you."
I BELIEVE HIM when HE SPEAKS! PRAISE GOD!!
Are you saying that Jesus promised eternal life to our mortal bodies? That our mortal bodies will never die? If you are, then I'm sure that is news to all the Christians THAT HAVE ALREADY DIED! We will have glorified and incorruptible bodies with which to spend eternity in Heaven with our Savior and God, but these mortal, corruptible, fleshly bodies? NOPE! Somebody has told you something that is not true.
I Corinthians 15:50-54
Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption. Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal must put on immortality. So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
