2 Corinthians 3:3 – And you show that you are a letter from Christ delivered by us, written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts.
Paul is telling the Corinthians that a letter of recommendation or outward change is not required to preach/teach the gospel. Lives changed by the Spirit of the living God from the inside out is a reflection of Christ. When the power of the Spirit comes in and changes a believers heart, that is what God cares about rather than credentials.
Let me remember that the internal condition of my heart toward others is more important than any outward manifestation of my religion. There is not a set of teachings nor things I can do to earn the grace of God. Grace is a gift from God through faith in Jesus. When we surrender and place our faith and trust in Jesus, the Spirit changes our life and heart. We have the power to be a living letter for Christ when we walk in the Spirit.
Thank you for your love and the power of the Spirit to change hearts and lives. Let my life be marked by a heart changed by the Spirit to love you and others.
