We do not have to tell anyone that God will punish sin
They know
We just need to BE Christians
Humble, kind, honest, and loving
Never co-signing evil
But being in the world but not of it
Ezekiel 3:21
However, if you have warned the righteous man that the righteous should not sin and he does not sin, he shall surely live because he took warning; and you have delivered yourself.”
Ezekiel 3:20
Again, when a righteous man turns away from his righteousness and commits iniquity, and I place an obstacle before him, he will die; since you have not warned him, he shall die in his sin, and his righteous deeds which he has done shall not be remembered; but his blood I will require at your hand.
1 Thessalonians 5:14
We urge you, brethren, admonish the unruly, encourage the fainthearted, help the weak, be patient with everyone.
2 Thessalonians 3:15
Yet do not regard him as an enemy, but admonish him as a brother.
Titus 3:10
Reject a factious man after a first and second warning,
Romans 15:14
And concerning you, my brethren, I myself also am convinced that you yourselves are full of goodness, filled with all knowledge and able also to admonish one another.
