The gospel is to be preached to human beings, not as elect or reprobate, but as sinners, all of whom need redemption.

I planted, Apollos watered, but God gave the growth. So neither he who plants nor he who waters is anything, but only God who gives the growth. He who plants and he who waters are one, and each will receive his wages according to his labor.
1 Corinthians 3:6-8
