God was sorry/regretted/repented…so here we learn the meaning of repented. (the verse comparisons are listed below, different translations different words)
A repentant heart does not mean a perfect heart, but one that strives to do what is right according to God. If you are repentant, you are sorry for your sins, you regret that you have done them, and to ask for forgiveness of them, as well as strive to live as God would have you live, using the commandments as a guide line for your life. Above all you should love God with all your heart, soul, mind, and strength, and love your neighbor as yourself (Luke 10:27; Matthew 22:37; Deut. 6:5; Mark 12:30).
Some people say that it’s an instant change in a person, but they should instantly be completely perfect and righteous. Some say it’s a process, and God works in you over time to make you more like Him.
My experience and opinion towards this is that there is an instant change, the desires of your heart do change, you become eager to be like Him, but you will fail many times, before you become even close to being like Him, otherwise there would be no need for trials or tribulations in our lives, because we wouldn’t need them. God disciplines those who are His (Heb 12:6; Proverbs 3:12; Acts 17:11). There would be no need for this if we were instantly perfect/righteous. We are righteous via Jesus, when God judges us and looks upon us, it is Christ He will see, but as far as a literal state of our being, we are not perfect and righteous. This is where self righteousness comes in to play, people who think they are perfect or completely righteous are self righteous and there is purging that must be done in them by The Holy Spirit, to remove this. The Bible says that none are righteous, no not one, besides Jesus Christ, He is the only righteous one (Romans 3:10; Eccl. 7:20).
Hence why you come as you are! There is not a change in you that is expected to be perfect, but a life light that will help you through life and help you grow to be a better person than you once were. If you had or did know me before, the person I was and the person I am are polar opposites. I was not a good person, and even in the ways I was, they were nothing to what I have and will become. I might have been good in comparison to myself in some ways, but when put up against God was vile and filthy, even at my best and I still am. I am a work in progress and will continue to be so until I get to go home.
