I will put my laws into their minds and write them on their hearts. The book of Hebrews quotes Jeremiah to explain the New Covenant: God no longer writes His nature on stone but in your heart. Righteousness comes from within, not through external rules.
A mistake can feel like a setback, but your standing remains firm. Righteousness in the New Covenant is a gift you carry, not a goal you achieve. Your heart is the place where God's nature works.
Today you may trust: what God has placed in you holds, even on weak days.
