In other words – having my faith grounded on hope – that subjective hope that is found internally in me is strong even with there are no objective reasons for hoping.
Faith is past oriented. Faith is trust in a Person, God, but it is trust in God to be and to do what he had promised to be and do because of what He has already been and done. Hope (future oriented) and faith are overlapping convictions. Faith is trusting a person, and when you trust that person for something they promise to do in the future, it is indistinguishable from hope.
True faith that saves us is a sustained trust in God and His promises, despite some tough circumstances. God told Abraham that they were going to have a son and Abraham hoped against hope. He didn’t waver in believing God. He was fully persuaded that God had power to do what he had promised.
The faith of Abraham bore an exact correspondence to the power and never-failing faithfulness of God.
If it is the adherents of the law who are to be the heirs, faith is null and the promise is void. For the law brings wrath; but where there is no law, neither is there violation. For this reason it depends on faith, in order that the promise may rest on grace and be guaranteed to all his descendants, not only to the adherents of the law but also to those who share the faith of Abraham (for he is the father of all of us, as it is written, “I have made you the father of many nations”)—in the presence of the God in whom he believed, who gives life to the dead and calls into existence the things that do not exist. Hoping against hope, he believed that he would become “the father of many nations,” according to what was said, “So numerous shall your descendants be.” He did not weaken in faith when he considered his own body, which was already as good as dead (for he was about a hundred years old), or when he considered the barrenness of Sarah’s womb. No distrust made him waver concerning the promise of God, but he grew strong in his faith as he gave glory to God, being fully convinced that God was able to do what he had promised. Therefore his faith “was reckoned to him as righteousness.” Now the words, “it was reckoned to him,” were written not for his sake alone but for ours also. It will be reckoned to us who believe in him who raised Jesus our Lord from the dead who was handed over to death for our trespasses and was raised for our justification.– Romans 4:14-25
