Blessed the man whom you instruct, O Lord, whom by your law you teach, giving him rest from evil days. - Psalm 94:12-13
God is always faithful. Even if you have not been always prudent and faithful to follow and obey God's word, He remains faithful to you.
Be upright of heart in listening, understanding, learning, following, and obeying the Lord's instructions so that you may be blessed in all your days.
