Grace is when God gives you what you don’t deserve; Mercy is when God doesn’t give you what you do deserve. Goodness and Mercy from God is what you need most of all, but they are only found at the Cross. You've tried to cover your tracks in the past, but the record of your sins is recorded in Heaven waiting for you at the Judgment to come. Apart from God's mercy, you don't have a chance. You're as guilty as sin. If you die hugging your sins, you're going to get what you deserve.
Only the Blood of Jesus Christ, God manifest in the flesh, can erase the record of your sins before God. You've been caught red-handed, because God has witnessed all of your sins in the past. Your very soul needs cleansing. Just like a guilty person entering a jail or courthouse that has been accused of heinous crimes tries to cover his face; at the Judgment, you will want to run and hide your face, but there will be no hiding place before the White Throne Judgment.
Repentance is when you uncover your face, look God in the eye, and confess plainly, "Yes, these are my sins, I committed them all, it's all my fault too, not someone else, I'm a mess, I did it, I was wrong, I am in my very nature a sinner, my sin problem is all mine, my inward nature is so corrupt, what I have done shows what I really am, no good thing dwells in me, my sins were directly against You God, I am so guilty and deserve your wrath, but God be merciful to me a sinner, for Jesus' sake please have mercy on my ungodly soul."
You have committed transgressions against God's holy Law. You have crossed the line morally, and trespassed over a forbidden boundary and entered into forbidden territory morally. With your thoughts, words and actions, you have crossed the line; and those sins must be paid for by someone. Morally, you have fallen short of God's holy standard, and missed the mark. Surely every man is vanity. You've been way off target with your thoughts and words. The Law of God clearly reveals your guilty sinful nature within. Surely men of low degree are vanity, and men of high degree are a lie: to be laid in the balance, they are altogether lighter than vanity. Surely Christ's Salvation is nigh them that fear Him.
Every time you sin against God, you prove that you have inherited Adam's sinful nature. Whenever you are driving and you see a police car, you automatically bump your brakes, and then look in the rearview mirror to see if the blue lights come on, because you know you're probably guilty. Your main problem is stubbornness, rebellion, pride, self-will - an inward sinful corrupt nature which kicks at divine moral constraints and authority. Sinful self is what will damn you straight to Hell.
Nothing but sinless Blood can take away your soul's sin stains. Religion cannot do the job. The Blood of an innocent Sacrifice (The Lamb of God) must be sprinkled on your soul by the Holy Ghost Himself. Ye must be born again. Only God's Blood can purify a sinner within. The Atoning Blood of God manifest in the flesh was shed for the complete and final payment of your sins and guilt. Faith in His Blood is absolutely needful; count on Jesus' Blood to save your soul, and nothing else, that is all.
Once Christ's Precious Blood is applied to your soul, it will bring first pardon and then personal, practical purity which is what the Bible calls Repentance. Create in me a clean heart, O God, and renew a right spirit within me. The very moment you trust to the Lord Jesus Christ, God does a miracle and creates a clean heart within you out of nothing. Self-reform will not work, you cannot get your act together, you cannot help yourself spiritually. You have nothing pure to offer God at all, for you are a filthy sinner within.
God has to create a pure heart within you out of nothing, or there will be no hope or salvation for you. Be wise now - Come directly to the Lord Jesus Christ Himself by Faith in His Precious Blood, and bypass religion altogether.
