(Romans 3:23) For all have sinned, and come short of the glory of God;
No one is perfect, therefore, no one is without sin. We have all broken God’s commandments. This is called sin. The Bible says that this separates us from God.
(Isaiah 59:1 -2) Behold, the LORD’S hand is not shortened, that it cannot save; neither his ear heavy, that it cannot hear: (2) But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear.
