Ask, and you will receive, that your joy may be full. John 16:24
Because Father God has made us totally dependent upon Him, we need to learn how to receive. And why do believers receive? Glad that you asked. Because Father God has so much to give to us as His children.
If anyone is lacking in their walk with Jesus, [I would say that we all lack in some area of our lives] it is not because God is unwilling to give, but because our faith has not reached out to receive.
Therefore I say to you whatever things you ask when you pray, believe that you receive them, and you will have them. Mark 11:24
