Now faith is the substance of things hoped for, the evidence of things not seen. Hebrews 11:1

But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him. Hebrews 11:6

Bring all the tithes into the storehouse, That there may be food in My house, And try Me now in this,” Says the Lord of hosts, “If I will not open for you the windows of heaven And pour out for you such blessing That there will not be room enough to receive it. Malachi 3:10
