To answer those who argue original sin is not real because it is unfair, is honestly quite simple. All you have to do is first gently explain how we obtain original sin, and then use their logic against them. The following will explain the two. Because of Adam’s disobedience, all are sinners.
What then shall we say? That the law is sin? By no means! Yet if it had not been for the law, I would not have known sin. For I would not have known what it is to covet if the law had not said, “You shall not covet” (Romans 7:7).
Submit yourselves to God. Resist the devil, and he will flee from you. Draw near to God, and he will draw near to you. Cleanse your hands, you sinners, and purify your hearts, you double-minded. (James 1:7)
For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast (Ephesians 2:8-9).
I have said these things to you, that in me you may have peace. In the world you will have tribulation. But take heart; you have overcome the world. (John 16:33)
Do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. (Philippians 4:6)
