Greetings in that Divine and Most Precious Name of Our Lord and Savior Jesus Christ!
Repentance is a process, which is why God gives us the gift of Eternal Life, that me may find enough time eventually to come into pure repentance. If God were to just force our consciousness away from Sin, we would be robots, and God can't have a love affair or relationship with robots. God allows us free-will to be ourselves, and our free-will includes our passions and lusts. God acknowledges our inherent weaknesses, which is why He has compassion, and sends us Grace. If God were so insistent on punishing sin, we would drop dead at any instance with the retribution and divine punishment of Zeus' lightning bolts striking us down! That being said, we have to be careful how hard we are on ourselves as we live through this process. For example, focus on the positive, on the growth, and the change, on the day by day getting closer to God. If you focus on the Sin, the Devil wins, because Sin divides us and temporarily distances our awareness of God. When we are focussing on our sins and their weight, we are not seeing the goodness of God in our lives, in the hopelessness of grief we feel forlorn and abandoned even. This becomes a self-reinforcing cycle of more and more sin. Just like King David went from lust, to adultery, to murder! To avoid Sin, we have to hope on God, and be careful how harshly we condemn ourselves. Repentance involves self-judgement, true, but not necessarily self-condemnation, because in reality, the human reflex reaction to pressure is to rebel. If we pressure ourselves to highly, we will only rebel against ourselves in the long run.
I highly recommend this book by His Holiness Pope Sheounda III of Alexandria (peace be upon him) titled "The Life of Repentance and Purity" where HH discusses in detail the process of repentance across the long arc of our lives, and also describes how we must cooperate in synergy with God by GRACE to be healed from sin over time. It means being honest with ourselves, accepting our limitations, and glorifying our accomplishments with God each new day.
Always remember that if we find ourselves in Sin, we can stop, and Sin is not so overpowering that is negates the good in our lives. Further, human beings are inherent control freaks, sometimes our desire NOT to Sin is as much a matter of sinful pride as it is sincere repentance, so we have to also give God the opportunity to change our lives by His efforts, and not our own force of will.
Even if you do not proceed towards the salvation of your soul, God who loves, proceeds with His grace to save you; He is the one who begins. God only asks you to respond to His voice within you. He wants you to work with Him when He starts to work in you. He wishes that when you hear His voice you do not harden your heart. Hence the visit of grace will lead you to repentance, as it led many. The visits of grace give every sinner a burst of hope. He is assured that God loves him, and that He will care for him, and He will search for him just like the Good Shepherd searched for His lost sheep. If, as a result, there are no feelings in the heart of this sinner, to lead him to repentance, then God will plant in his heart these feelings by the work of His grace. He will prepare all of the means which make his heart move towards repentance. Life of Repentance and Purity
