The very nature of ‘Grace’ is intended to be without any payment attached with it. It is so, because we were so utterly lost to sin, that we could not do anything about it. The only way out was, that God pay the price for our forgiveness, and offer it to us freely by grace. We could not earn it, nor could we buy it. Simply not possible.
Mind you, forgiveness through grace is free, but it hasn’t come cheap. It costed God His everything. So do not neglect it, nor take it for granted. Live worthy of the grace bestowed on you, and lift up the LORD who is gracious towards you.
