Beloved, have we confessed our sins to God and turned away from doing them which is repentance? Do we not realize that keeping that sin buried and unconfessed breaks our fellowship with God and benefits of HIS presence? Thank GOD for any who have confessed our Lord JESUS as Savior, if we sin and confess those sins, those sins are forgiven and our life is spared so you can live on. Achan and his family were stoned and burned in the old covenant, an end way worse than what God now has redeemed us to. Nevertheless, now, unconfessed sin has it adverse consequences. So repent, confess your sins and return to fellowship with God.
Joshua 7:19 (Read verses 19-26 for full context)
19 Now Joshua said to Achan, “My son, I beg you, give glory to the Lord God of Israel, and make confession to Him, and tell me now what you have done; do not hide it from me.”
1 John 1:9
9 If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
