But your iniquities have made a separation between you and your God, And your sins have hidden His face from you so that He does not hear. Isaiah 59:2
Sin separates us from God, if you want to know why your sin is a serious issue, this is the first issue. God is Holy and cant be in the sight of Sin. When we continue to live our life in sin and never change, we are separated from God
This is the issue the Jewish people had throughout the Old Testament, everytime God got close to them again, they would go back to their sinful ways. Christians seem to be ever more guilty of this. Because we live under Grace, many Christians don’t take Sin serious enough.
And He saw that there was no man, And was astonished that there was no one to intercede; Then His own arm brought salvation to Him, And His righteousness upheld Him. Isaiah 59:16
However because God loves us enough, he sent Jesus Christ (his own arm) to bring salvation (Jesus) to everyone who repents and believes in Christ.
Our Sin separated us from God, our sin was leading us to certain death. But because Jesus was willing to intercede for us, take the penalty for our sins, we can obtain salvation through Christ
Its only by the blood of Christ, we can come to the Father because alone we are not worthy Amen!
