For Tulip-Deniers, Regeneration is not an act of God's Grace, but a reaction of God to the sinners who employed their ability to meet the condition/command of placing faith in Christ; Like their mother-Rome, and cousin-Mormon, grace gets them started, but it is up to them to make the most of God's offer, and in the end it is the sinner's ability to make the difference.
2 Nephil 25:23.....for we know that it is by grace that we are saved, after all we can do. (throw the term grace around, but redefine it)
