“Who against hope believed in hope, that he might become the father of many nations, according to that which was spoken, So shall thy seed be.”  
Romans 4:18

The word of God is so important in your sojourn on the earth; with the word of God you can create your experiences, the word of God becomes your anchor in trying circumstances, when spoken, becomes your shield to quench all oppositions.
When the world tells you the situation is hopeless, with the word of God, you can create hope!
The main verse said when God told Abraham “…so shall thy seed be”, he used that word and became hopeful even though he carried the very source and stigma of hopelessness every where he went- ‘his own body, now dead!’
“And he brought him forth abroad, and said, Look now toward heaven, and tell the stars, if thou be able to number them: and he said unto him, SO SHALL THY SEED BE.”  Genesis 15:5
Remember, God already gave Abraham a picture to hold on to with that word, so anytime he saw his body or remembered his wife was not just old, she was barren, instead of fixating on those pictures, he quickly focused on the picture of the stars- his children that he could not count.
Instead of staring down at himself in despair, he looked up to the stars in hope; despite the fierce biological opposition, he won!
Don’t discard the picture of your fulfilled purpose; wealth and increase, that picture of your oneness with the word fully expressed, hold on to it!
“…hope maketh not ashamed…” Romans 5:5
