Hebrews 11:1-2 Faith is the confidence that what we hope for will actually happen; it gives us assurance about the things we cannot see. Through their faith, in the in days of old earned a good reputation.
This chapter goes on to tell us about how Able had faith, Enoch had faith, Noah had faith, Abraham had had faith, Sarah had faith. The faith of these people are why we even know about them today. A more modern version of great faith was Mother Teresa... a lady of faith was constantly taking care of people's needs one tiny need at a time... now she is know around the word.
When we have faith that God will do what He says he will do it makes it much easier to do what He tells us to do. The more we get to know God the great our faith becomes... the more we know God the more aware we become that the good things happening in our lives come straight from God. The more aware we become the stronger our faith becomes. When we have faith in God and do what he ask us to do, God will make sure that we earn a good reputation. Everybody may not like us...but everybody will know that we are a child of the most high God. Like us or not they will know that we choose God and we choose to make choices that honor God
We just can't go wrong by choosing God. God is so good. God loves us so much and would only choose good for our lives. Our lives and our reputations can only grow in goodness when we choose to have faith in all that God promises. When we have faith we don't have to know what tomorrow brings we get to just trust that whatever that might be God is on our side and will take care of us and our reputation.
