Give thanks to the Lord, for he is good. His love endures forever. Give thanks to the God of heaven. His love endures forever.
Psalm 136:1 and 26 NIV
Our thanks arises from the nature of God and his glory and goodness. The steadfast reason we give thanks is because God is good and his love is inexhaustible, beyond decay, and never ending.
God, thank you for sending Jesus as the demonstration of your love. I love you Father. I love you for who you are and what you have done. I love you for what you have promised. I love you for the blessings you shower upon me. I love you for giving me hope. I love you because you first loved me. I love you because you are worthy of all love. But I confess that my love is not as strong as yours, so please, fill me with your love by the power of the Holy Spirit. Through Jesus I lift my heart to you. Amen.
