Heb. 10:38 -Christian is to walk by faith, not by feelings or emotions. We are naturally disposed to live by our feelings and emotions, and to react according to life's confrontations. When emotional we react according to the emotion; when we feel bad, we react irresponsibly: grumble, complain, murmur. If we feel good, we act happy. Our behaviour is determined by how we feel and react to emotional experiences. Living by one's feelings is contrary to God's will. "The just shall live by faith". . this is God's will. Faith is to control our life and to face life's particular problems according to God's word, and not by our feelings.
How does a believer live by faith? What does it mean to live by faith? It means to do four things, and that, consistently.
The Description of Faith:
The key to any of us being great in the eyes of God is faith-faith in His Son , the Lord Jesus Christ.
Faith is the substance, the actual possession , of things hoped for, the evidence and reality of things not seen. It is both an act and a possession of the thing believed. It is believing and trusting in that which actually exists-in that we can possess it. We may not be able to see it, but it is real and existing, and we can possess it by believing and having faith in it. We can possess it now-we cannot see it, but we can actually possess the very substance of it by believing and entrusting our lives to it.
The reward of faith is God's approval, and when God approves us, He accepts us into His eternal Presence. This means that God looks after and cares for us, giving us victory over all the enemies of this world -including death-and He does it for eternity. The approval of God means that God fulfills all His promises to us, and the promises of God become a living reality in our experiences, both daily and eternally.
