I can tell you first hand that just when I am down, when I feel my lowest,someone comes along. Or a song comes on. Or the birds start singing. But a God rescue is put before me. It is a spiritual connection like no other. When angels come forth, you overcome that heaviness. Your spirit is lifted once again. God is good.
Hebrews 1:13-14 But to which of the angels said he at any time, Sit on my right hand,until I make thine enemies thy footstool? Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation?"
