Faith is the substance of things hoped for, the evidence of things not seen.
The New International Version says, Faith is being sure of what we hope for and certain of what we do not see. That is pretty clear. But it becomes even more clear when you plug that definition into 1 Timothy 6:12,
Fight the good fight of [the substance of things hoped for, the evidence of things not seen. Fight the good fight of being sure of what you hope for and being convinced of what you do not see.]
When the answer to your prayers is not on the horizon, when you don't feel differently, you need to fight the good fight and say, "You know what? God's Word says it and that's all the evidence I need. It is the evidence of things not seen, and I'm going to stand on that truth. I don't care what the world says, I don't care what circumstances say, I am going to fight the good fight of the substance of things hoped for, the evidence of what I do not see."
And you stay with it until, as they say, "Faith turns to sight."
What are you struggling with today? What challenge is testing your faith? Stand firm on the truth of God's Word. Trust Him, no matter what others may say.
Real faith is standing firm in the midst of the storm. So stand firm!
