Summary: To show that JESUS CHRIST is our Gift here on this life on earth and on to eternal life.
Romans 6:23 (Amplified Bible)
For the wages which sin pays is death, but the [bountiful] free gift of God is eternal life through (in union with) Jesus Christ our Lord.
Romans 6:23 (King James Version)
For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
Just like in John 10:10, destruction was already in the world because of the fall of man. Now the solution comes next. Just like there's a problem, then there's a solution. The solution to the problem will not be sought after because we have not yet encountered the problem. But even there's a problem, the LORD JESUS is always the solution to our problems. It's like employer and employee relationship, sin is a terrible and evil employer, when you work for it and promoting it's effects, like an evil employer: sin pays you with death, that's the payment of every work or toil you give to it. But the free gift is not compared to the compensation where you have to work for it, it's grace, it's a gift, you don't deserve the gift, but it's given to you anyway because it's based on the generosity of the Giver: the LORD JESUS CHRIST to give you the gift of eternal life. Grace is incomparable with sin, there's no point to compare it. It's eternal life with the LORD JESUS CHRIST while here on earth our relationship with the LORD. The pleasure and profit of sin as so-called and enjoyed by this dying and corrupted world because of the enemy is not deserving to be called fruit. Sinners or unbelievers does work to be paid with death by sin, namely: (1) ploughing iniquity, (2) sowing vanity, and (3) reaping the same. Therefore whatever they do will end up in death. Imagine a very wealthy person sowing in charities with his millions of money but got surprised when he ended up in hell when he died. It's because every person born in this world are imprisoned in a jail cell called sin, whatever they do, they might sing, dance, and do dramas but still they are a prisoner. There's another prison called "GOD's Grace" and whatever the prisoners do there end up in life. Thus we are called "slaves to righteousness"
Romans 5:12 (Amplified Bible)
Therefore, as sin came into the world through one man, and death as the result of sin, so death spread to all men, [no one being able to stop it or to escape its power] because all men sinned.
1 Corinthians 6:9-10 (Amplified Bible)
Do you not know that the unrighteous and the wrongdoers will not inherit or have any share in the kingdom of God? Do not be deceived (misled): neither the impure and immoral, nor idolaters, nor adulterers, nor those who participate in homosexuality,
Nor cheats (swindlers and thieves), nor greedy graspers, nor drunkards, nor foulmouthed revilers and slanderers, nor extortioners and robbers will inherit or have any share in the kingdom of God.
Galatians 3:10 (Amplified Bible)
And all who depend on the Law [who are seeking to be justified by obedience to the Law of rituals] are under a curse and doomed to disappointment and destruction, for it is written in the Scriptures, Cursed (accursed, devoted to destruction, doomed to eternal punishment) be everyone who does not continue to abide (live and remain) by all the precepts and commands written in the Book of the Law and to practice them.
