Jesus Christ is the only known character His word and act have no different border 

credit of Jesus Christ as the only God Son, determines the miracles that He has done

otherwise two poles of spiritual power would have taken shape, which consequently would have hurt both sides to the benefit of enemies of God, moreover the mission of John was just to introduce Jesus as the heavenly Father's Son, and then all was to leave to Jesus up to His death and resurrection, and later on to His apostles and all followers, so in the life course everyone performs his/her role and once it is short and once it is long, but it is never forever, and that is why that John was to decrease.

how you do not know whatever is born once dies

bodily turns into dust and on wings of wind flies
