Currently I am reading a small booklet called Justification: Being Made Right With God by Guy Waters. This is a great resource if you want to know more about the truth of justification. In one section the author talks about sinners being able to have peace with God through justification. He quotes Romans 5:1: "Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ." He speaks clearly that this peace is given as a gift from God to those who put their faith in Christ. This isn't a peace like we hear about in our world. It isn't some inner feeling but rather a hope and trust in our Savior. This is a peace that cannot be taken away because it is a peace with God that comes from God. The author writes:
"The reason we will never lose our peace is not our firm grip on God. Our peace in Christ stands firm because of God's grip on us."
The God of the universe is holding us firm therefore our assurance of peace should not waver. We ought to constantly remember our great God's promise that "since we have been justified by faith, we have peace with God through our Lord Jesus Christ." Peace comes from knowing our sins have been forgiven and Christ's perfect righteousness has been imputed to us by God's grace through faith.
Grace upon grace,
