God's Promise Rests on Grace

Romans 4:13-16, 23-5 "For the promise to Abraham and his offspring that he would be heir of the world did not come through the law but through the righteousness of faith. For if it is the adherents of the law who are to be the heirs, faith is null and the promise is void. For the law brings wrath, but where there is no law there is no transgression." It's not our performance that matters. It's the performance of Jesus Christ. God raised him for us who believe and makes our lives worthwhile. Ronnie is feeling distant from God and wondering how he can get back.How can you know that there's still grace for you after a period of sin?
