Israel, the Jews are the chosen people of God. They denied our Lord and were idolaters time after time. They went their own ways. They suffered and still do. God let them go their own way. He has not cast them away forever. He will restore and save a remnant along with all believers.
God promises in His Word, I will cleanse you from all your filthiness and from all your idols. I will give you a new heart and put a new spirit within you; I will take the heart of stone out of your flesh and give you a heart of flesh. I will put My Spirit within you and cause you to walk in my statutes and you will keep My Judgements and do them. Then you shall dwell in the land I gave your fathers; you shall be My People, and I will be your God. Ezekiel 36:25-28 Then the nations which are left around you shall know that I the Lord, have rebuilt the ruined places and planted what was desolate. I, the Lord, have spoken it, and I will do it. Ezekiel 36:36
All those generations and we still have idol worship. All we ever have to believe is that Jesus Christ died for our sins and repent, and obey… He will give you a new heart to obey. He will turn you away from sin. You cannot do this yourself. Not one of us will ever be good enough. We all deserve death. He has chosen to give mercy on who he will give mercy. There is nothing in you that can help you. We cannot earn our way to Heaven or think we are good enough. You must be born again. Unless you are, you will not see the kingdom of God. John 3:3 Plain and simple. You must believe and lose your life to gain it. To follow his Word, daily, pray, take up your cross daily and obey, repent your sins. It is an inward change, that cannot be faked. God knows all men’s hearts. There will come the final day. You will know that He is God. You will try to hide yourself. Even if you die before the second coming, you will face the final judgement. If your name is not written in the book of life, you will perish. All of us fall short of the Glory of God. God tells us to be ready, because no one knows the date or time. He will come like a thief in the night. Are you ready? If not, it will be to eternity in hell. No choice is the same, hell.
