“The work of God is this: to believe in the one he has sent” (John 6:29).Therefore, my dear brothers, stand firm. Let nothing move you. Always give yourselves fully to the work of the Lord, because you know that your labor in the Lord is not in vain (1 Corinthians 15:58).
The fullness of joy comes not from the fruits of labor but on the love of Jesus. His love for you comes with abundant and fruitful blessings. Remain in His love and your joy will always be full and complete.
