Through God’s Spirit, Joshua knew the people would not be able to serve the Lord regardless of their professions of faith. God is a jealous God and will not, cannot forgive without a repentance and an atonement for sin.
19 But Joshua said to the people, “You cannot serve the Lord, for He is a holy God. He is a jealous God; He will not forgive your transgressions nor your sins. 20 If you forsake the Lord and serve foreign gods, then He will turn and do you harm and consume you, after He has done you good.”
PRAY FOR THE SALVATION OF ISRAEL.
