Faith means the absolute believe that GODS ABILITIES ARE NOT FINITE. All things are possible if we believe.
Jesus cured those who believed and NOT those who doubted.
Faith is hope for the unseen. Actually Heb 11:1 says Now faith is assurance of things hoped for, a conviction of things not seen
We are assured of what we hope for, whether its healing, deliverance etc
When you aver that there are conditions we have no choice, you limit the capabilities of God and this breeds doubt.
Through faith God gives us the power to affect circumstances. When we place unwavering faith in God through Jesus Christ, the world will be affected. This is a promise from the Lord.
But if faith means insisting on being in control over things you are not in control over, to each his own.
