When you receive something you have prayed for in the name of Jesus, but not sure if it’s from God, remember — you prayed for it.
Trust in Him, His word, and His promises will confirm that it’s from God.
John 14:14 (KJV) – if ye shall ask any thing in my name, I will do it.
Proverbs 3:5 (KJV) – trust in the Lord with all thine heart; and lean not unto thine own understanding.
