First of all, what is Faith? There are a number of kinds of faith. Everyone, saved or unsaved, has a natural, human faith. But the faith I want to talk to you about is scriptural faith, the Bible kind of faith. There is a big difference between believing with our heart or just believing what our physical senses tell us! Faith operates in a realm that is beyond human reasoning.
It's the substance of things hoped for, the evidence of things that we can't touch, hear or feel, (Hebrews 11:1). We don't need to use our faith for something we already have.
For example, we hope for physical strength to do the work that we must do, but when we don't have the strength, faith says, "The Lord is the strength of my life; of whom shall I be afraid" (Psalm. 27:1). If we have financial struggles and don't have the money to pay all the bills at the end of the month, faith says, "But my God shall supply all of my needs according to His riches in glory by Christ Jesus", (Philippians 4:19).
If we trust in ourselves, we will probably spend a lot of time reasoning and worrying. If we place our faith in other people, we will probably spend a lot of time being disappointed. What we put our trust in is our choice, but as believer, God's Word makes it clear that our faith should be in Him and Him alone!
Jeremiah 17:7 says, (Most) blessed is the man who believes in, trusts in, relies on the Lord and whose hope and confidence the Lord is.
I believe that God has given each of us enough faith to do whatever He has for us to do. The key is learning to take steps of faith over time and through life's experiences, to use what we've been given and cause our faith to grow.
What Faith isn't, it is NOT A FEELING!
