So if I surrender my life to God, will my life be easier?

Yes, in a way. Jesus never promises us that we won’t have pain again once we trust Him with our lives. In fact Jesus actually promised the opposite. He said that the world will hate you and persecute you because of your love for Jesus. Not exactly what we would call easy. However, God does promise care, guidance, and peace when you trust Him with your life. Proverbs 3:6 says that God will make your paths straight. He will guide you in the decisions and choices of life and lay out the path for you. Philippians 4:7 promises peace in all circumstances of life, even pain. And the care comes from a loving Father in Heaven who cares for his children so much that He knows how many hairs we have on our head. He knows us better than we know ourselves and that gives Him the ability to care for us in our lives. So while trusting in Jesus will not take away pain in life, it will be easier with the guidance, love, and care of the Father in heaven to live life. And this is the way that I can answer, “Yes your life will be easier when you trust God.” But please don’t think I have said that you will never have pain, struggles, or hard decisions again. With God these moments of pain in life become easier.
