God has promised to be faithful to you so there is no need to fear failure. The reason we don’t need to be afraid of failure is because our sovereign God has promised to be faithful to us. Look at how God addresses our fear. He says in Deuteronomy 31:6, “Be strong and courageous. Do not be afraid or terrified because of them, for the LORD your God goes with you; he will never leave you nor forsake you.” He says in Lamentations 3:22-23, “Because of the LORD’S great love we are not consumed, for his compassions never fail. They are new every morning; great is your faithfulness.” And in 1 Corinthians 1:8-9 God says, “He will keep you strong to the end, so that you will be blameless on the day of our Lord Jesus Christ. God, who has called you into fellowship with his Son Jesus Christ our Lord, is faithful” (emphasis mine).
By grace, God uses us in spite of our failures, not because we are free from failures. We need to understand that God sovereignly works through our weaknesses and even our helplessness to accomplish the work He has given us to do.
God is not expecting us to do, or become, or save in our own strength. God assures us that no matter how big the task, how bleak the circumstances, or how useless we feel, the Holy Spirit is going to work through us so that we will do everything the Father has planned for us to do. Our confidence comes from God’s abilities, God’s resources, and God’s strength, not ours.
God wants you to know that you don’t have to be afraid of failing at what God wants you to do. He has promised to be with you wherever you go. God is never going to leave you. He is never going to forsake you. He is always going to be with you wherever you go. We don’t need to worry about failing because God has promised to give us everything we need and to do all that needs doing so that He will accomplish His work through us.
