You can never have faith to believe for something if you don't know God has promised it to you in his Word. This is why all the promises of God are "yes". We are only asking for the things God has already given to us. You need to find out what those things are first before you ask.But what I'd you ask for something that God does not want you to have? Then He says no, and that is the point I am trying to make.
2Pe 1:3 According as his divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue:
2Pe 1:4 Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust.
