Let God
Ever since I can remember I've heard the saying, "God helps those who help themselves." To those who don't understand the Word of God, it sounds lofty and good because it's really an excuse for their not wanting God in their lives.
It's also true that God does expect us to do what He places before us to do. God is not pleased with our shirking any responsibilities that are ours to do. However, there comes a time when, in our own self-confidence and zeal, we keep pushing ahead, only to find our efforts resulting in frustration and emptiness.
The problem may be that you have tried to help God instead of letting Him help you. At times, God may need to demonstrate to us our need for His ability in our life. To remind us that He is our source of creativity, strength, and wisdom: for in Him we live and move and have our being as also some of your own poets have said, "For we are also His offspring" (Acts 17:28, KJV). The glory and honor should go to Him when we experience success – not to ourselves.
God loves you and wants to answer your prayer. Say this prayer with me:
Father, tonight I have come to the end of myself and release my efforts and labors into Your hands. Forgive me for trying to accomplish anything without totally submitting it to You. I recognize You as Lord of my life. I love You and thank You for showing me a better way. In Jesus' Name, Amen.
