It is God who created us for his good pleasure and he has already provided everything that we need to accomplish his plan and purpose. God is not the author of confusion so he would not ask us to do something if he has not already made a way for us to accomplish it. We may not be able to see the way but our requirement is faith. Although the way seems impossible, we are required to have faith that God is able to do what he has promised.
We increase our faith through our study of the word. Faith comes by hearing, and hearing by the word of God. (Romans 10:17) During difficult times and when we struggle to stay in faith concerning what God has said, we study the word to gain strength. Study and be eager to do your utmost to present yourself to God approved (tested by trial), a workman who has no cause to be ashamed, correctly analysing and accurately dividing the word of truth. (2 Timothy 2:15)
Faith requires hope in things that we cannot see. If we can see it then it does not require faith and when it seems impossible is when God does his best work. He specialises in the impossible and he is waiting for our declaration of faith for his work to be manifested in us. Abraham did not waver through unbelief regarding the promise of God, but was strengthened in his faith and gave glory to God, being fully persuaded that God had power to do what he had promised. (Romans 4:20-21) So stay in faith and keep believing.
