Jn 15:16 You did not choose Me, but I chose you and appointed you that you should go and bear fruit and that your fruit should remain, that whatever you ask the Father in My Name He may give you.
Ever ask God for something in the Name of Jesus and not get it? Be honest.
Are you bearing the fruit God has appointed you to bear? If not, could that be why? God's word is true. But we must do our part. What we ask for must be in God's will. He's not gonna give you anything that is against His will. And you must be bearing the fruit He has for you to bear.
