"Therefore he is able, once and forever, to save those who come to God through him. He lives forever to intercede with God on their behalf." (Hebrews 7:25)
Only through Jesus can the divide between us and God be bridged. "And by that will, we have been made holy through the sacrifice of the body of Jesus Christ once for all." (Hebrews 10:10) With Jesus' death on the cross for the forgiveness of OUR sins, a pathway to salvation was created. Are you on that path? Repent and surremder your life to Jesus. For when you do, your old life will die, "Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here!" (2 Corinthians 5:17)
A new life you will have, "Yet now he has reconciled you to himself through the death of Christ in his physical body. As a result, he has brought you into his own presence, and you are holy and blameless as you stand before him without a single fault." (Colossians 1:22) You will now be "sinless" in front of God on judgement day, no matter WHAT your past. This in no way could have been "earned" on your own, but it instead was a gift to you through Jesus' sacrifice and God's grace.
"For when I tried to keep the law, it condemned me. So I died to the law--I stopped trying to meet all its requirements--so that I might live for God." (Galatians 2:19) It isn't about trying to live a "perfect" life. Good thing, because that would be impossible! When you accept Christ, "Sin is no longer your master, for you no longer live under the requirements of the law. Instead, you live under the freedom of God's grace." (Romans 6:14)
You will still stumble, but that's okay, "I do not set aside the grace of God, for if righteousness could be gained through the law, Christ died for nothing!" (Galatians 2:21) Jesus not only died for your past sins, but also those of today and the ones yet to come. You will fail at times, but guess what? He NEVER will! For even, "If we are unfaithful, he remains faithful, for he cannot deny who he is." (2 Timothy 2:13)
Live a life of love and promote God's glory in ALL that you do. For it is said, "He has shown you, O mortal, what is good. And what does the LORD require of you? To act justly and to love mercy and to walk humbly with your God." (Micah 6:8)
