A few days ago I was reading the Bible and once again, something it said just jumped out at me and struck me in a way it never has before. "Against all hope, Abraham in hope believed..." This was in the book of Romans and it was talking about how Abraham believed and had faith in something God told him would happen, even when it looked humanly and physically impossible! Abraham and his wife were well beyond the child-bearing age and Sarah had not been able to have a baby yet. He was 100 and she was 90. In my mind, there's no way this couple would be having a baby. But God told Abraham that he would be the father of many nations and his descendants would be as many as the stars in the sky. Abraham didn't weaken in his faith and he believed that God had the power to do what he said he promised. And it happened -- Sarah gave birth in her old age and that was the beginning of the Jewish nation. God keeps his promises.
Do you sometimes have situations in your life that look completely hopeless? Remember Abraham's faith and belief in God's promise even when it didn't seem possible. Against all hope, Abraham in hope believed. If God has promised us something in his Word, we need to have faith that he is able to keep his promise. I don't think this means that because we want something to be a certain way that it will happen just because we say we have faith. But I think it means that if God promised something in scripture, it will happen and we just have to have faith in his promises. Do you have any personal experiences where something looked hopeless, but God kept his promises?
...who, contrary to hope, in hope believed, so that he became the father of many nations, according to what was spoken, "So shall your descendants be." And not being weak in faith, he did not consider his own body, already dead (since he was about a hundred years old), and the deadness of Sarah's womb. He did not waver at the promise of God through unbelief, but was strengthened in faith, giving glory to God, and being fully convinced that what He had promised He was also able to perform. And therefore "it was accounted to him for righteousness." Romans 4:18-22
