We have the right to use the Name of Jesus when we pray, praise and worship! That Name was given to us, the church and it has not lost its power.
John 14: 12-14, “Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater [works] than these shall he do; because I go unto my Father. And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. If ye shall ask any thing in my name, I will do [it].”
Jesus was really saying that you are to take His place here on earth, and He will be your representative in heaven. Mark 16:17, “And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues.”
