IF it is from Gods kindness and ability to perform it is rock solid since you could never ever find a flaw in Gods kindness or his ability to perform. By trusting Jesus his perfection and holiness becomes our ally instead of standing over us like a giant boulder ready to crush and judge us. The same unrelenting power that was convicting and holding you accountable for your sins and insisting on justice then works for you as it forces the justice due Jesus because of his unjust treatment at the cross. God is righteous for making the sinner righteous since a righteous man died in the place of the sinner. What was once your inescapable doom is now your inescapable salvation. Like if all the police force was trying to catch you and lock you up but now it it fighting for you freedom and your absolution of all guilt. God’s judgement working for you instead of against you. We have a very very smart God. With faith in Jesus substitution on your behalf God is moving to free you completely in every way from all guilt and the consequences of sin, just as before he was moving to implement the slow plodding drumbeat of death, the ultimate judgement of your sin.
If it was from works you would have a shaky foundation since you could mess it up today, and we could always find some flaw in anyone’s record of works. Since Our salvation relies on the perfect performance of Jesus and not our own, we can put all of our hopes into God’s ability to perform for us and in us instead of our own power and works.
This puts us on a very strong foundation! Rock solid since it does not rest on us but Gods ability to perform and his kindness to see it through to the end . As we live our lives we can “draw from the vine” trusting Jesus to “live in us as we trust in him.” This allows us to be good where before we kept repeating the bad things we did and THOUGHT over and over again. By consistent constant trust we can opt out of the whole sin and death system. By the knowledge and faith in what he has said and promised us we can believe only for the best and reject thoughts and circumstances that are out of line with what Jesus purchased for us. Jesus took our judgement of doom and separation and we get Jesus judgement of Son ship and eternal love as a son of God. All of Gods power to enforce ultimate justice working on our behalf.
And since it is through God’s kindness, then it is not by their good works. For in that case, God’s grace would not be what it really is–free and undeserved. Romans 11:6
