These verses can give us great insight into what it takes to combat doubt and fear in our lives.  The first part gives us clear directions as to what our responsibilities are.  We are to be steadfast trusting in the Lord at all times…calling on Him first, and not as an afterthought.  We are to turn our back on our old sinful ways, but even more importantly, it says  we are to not tolerate or enable sin to remain in our house.  This is called compromise, and unfortunately many a Christian household has crumbled when questionable moral concessions have been made.  As we work on our responsibilities, we can as Job 22:26 says,  ” Find delight in the Almighty and lift up our face to God.” For when there is no longer the guilt and shame of sin weighting us down, we can lift up our head and look straight into the eyes of Jesus with a clear conscience…free of self-doubt and fear.
