What a powerful promise! Whatever we ask In His Name, we will receive!
Peter, after his conversion, understood the magnitude of the birth, life, death and resurrection of Jesus.
Before Jesus' crucifixion, He taught the disciples the importance of praying in the proper way:
Hitherto have ye asked nothing IN MY NAME; ask, and ye shall receive, that your joy may be full. (John 16:24)
And in that day ye shall ask me nothing. Verily, verily, I say unto you, Whatsoever ye shall ask the Father in my name, he will give it you. (John 16:23)
Don’t get this great promise confused. This promise has to be taken along with the other principles of prayer taught in the Bible. We can never isolate one verse on a subject without considering all that is taught on that subject in the Word of God. For example, the Bible teaches you cannot ask selfishly:
Ye ask, and receive not, because ye ask amiss, that ye may consume it upon your lusts. (James 4:3)
There are conditions:
The effectual fervent prayer of a RIGHTEOUS man avails much. (James 5:16)
