I Corinthians 15: 57-58 reminds us ...
"... thanks be to God, which giveth us the victory through our Lord Yeshua the Messiah (Jesus Christ). Therefore, my beloved brethren, be ye steadfast, unmovable, always abounding (!!) in the work of The Lord, forasmuch as ye know that your labor (for / to win souls for His Kingdom) is not in vain *in* The Lord."
I Corinthians 15: 50-54 also speak of victory ...
"Now this I say, brethren, that flesh and blood cannot inherit The Kingdom of God; neither doth corruption (that which is able to die; the *flesh*) inherit incorruption (eternal life). Behold, I show 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 (in Messiah) 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 (body of the flesh) shall have put on incorruption (immortality),a nd this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory."
The Lord is the Victor over death.
He alone holds the keys to death and hell, now.
We can trust Him Who is True.
He alone is able to deliver these mortal bodies into (as He changes them into incorruptible spiritual bodies) immortality.
I John 5: 4 shares with us ...
"For whatsoever is born of God (our Father in Heaven, YHWH, the Almighty, the God of Abraham, Isaac and Jacob / Israel) overcometh the world (system): and this is the victory that overcometh the world (system), even our faith."
I John 5: 5 - 13 continues ....
"Who is he that overcometh the world (system), but he that believeth that that Yeshua (Jesus) is The (True, Only-begotten) Son of God (YHWH)?
"This is He that came by water and Blood, even Yeshua the Messiah (Jesus Christ); not by water only, but by water and Blood. And it is The (Holy) Spirit (of YHWH) that beareth witness, because The (Holy) Spirit is Truth.
"For there are three that bear record in Heaven, The Father, The Word, and The Holy Ghost (Spirit): and these three are one.
"And there are three that bear witness in earth, the spirit, and the water, and the blood: and these three agree in one.
"If we receive the witness of men, the witness of God is greater: for this is the witness of God which He hath testified of His son.
"He that believeth on The Son of God hath the witness in himself: he that believeth not God hath made Him a liar; because he believeth not the record that God gave of His Son.
"And this is the record, that God (the Father Almighty) hath given us eternal Life, and this Life is in His Son.
"He that hath The Son hath Life: and he that hath not The Son of God hath not Life.
"These things have I written unto you that believe on The Name of the Son of God; that ye may know that ye have eternal Life, and that ye may believe on The Name of The Son of God."
I John 5: 20 ... shares more truth, for those who believe ...
"And we know that The Son of God is come, and hath given us an understanding, that we may know Him that is True, and we are in Him that is True, even in His Son Yeshua (Jesus) the Messiah (Christ). This is The True God, and eternal Life."
He has already won the victory over death, and over this world system in which we live, being on the earth as we are. He won it through His Life, suffering death, burial, and subsequent Resurrection from the dead! (on the third day after He died)
All we need do is realize we have no way to get to Heaven ourselves (on our own merit), after we die, because we were born unable to measure up to God's "mark" ... His standard of Righteousness, of sinlessness, of being pure in heart (on our own), of having a right attitude at all times, and in every motive of our hearts, ... and more, because He requires us to be holy, as He is holy, and we can only do that by being "in" Messiah, through our belief in His Name, and in His atoning sacrifice as the Lamb of God, in our place, to redeem us (each of us individually).
We can never do enough to earn our way into Heaven, or eternal Life, on our own, by ourselves.
We need a Redeemer, One Who is our kinsman-Redeemer (as Boaz was, for Ruth), Who is willing to "pay the debt owed" by our sins, and iniquities, in God's sight, ... to make us acceptable to The King Eternal (Melech ha Olam).
We must believe on The Name of The Son of God, Who took upon Himself our sins and iniquities, on the tree, the Roman execution stake. To do that, we can "call upon The Name of The Lord," and He will surely save us (deliver us from eternal condemnation) from the wrath to come. He promised. He cannot lie. He is The Truth! He will do it!
The victory has been won! Yeshua the Messiah has won it *for* us! Hallelujah!!! Let's (we who already believe) trust in Him, Who made us, has redeemed us, and will carry us through into eternal Life with Him, in Heaven!
