If we understand that no man will ever genuinely repent without the grace of God changing his heart, then we will not feel that we have to dilute the demands of the gospel. We will put our confidence in God. We will remember that, if God is displeased with us, He will not bless us. We will simply give the water of life to the sinner in its undiluted strength, believing that if he is one of God’s chosen God will help him drink it. [Samuel Waldron, Two Things You Must Do to Be Saved, 40.]

You need to read his explanation of that very topic in the book. He explains it well. If you want, I will photocopy it for you.
I agree with your knee-jerk response, but he has a good (and biblical) explanation.
