I have encountered healing and depression many times: there has to be dying before resurrection. "Daily pick up your cross and follow Me," is about death and resurrection. We struggle with depression because of fear of letting go and letting God. We are slow learners all of you, well all of us except God with us that is. One-thing you need to know: your in God's hands and His grace is sufficient. There are references of this One-thing in the bible:
"One thing is needful and Marie has chosen that good part that will not be taken from her."
That good part is Grace to forgive her old life and Love much: we would say Grace to receive forgiveness and change, but the reality is becoming one Spirit with God and we are slow learners.
Another example "This One thing I do, forgetting what lies behind (dead) I press on,"
To go on to know the lord: we don't know God in our understanding and that's why it's difficult for us. We need to get past our understanding and imagination: that's what praying in the Spirit is about. Praying in unknown tongues gets us past what we think we know, to be in agreement with God. We enter his presence with thanksgiving and it's better said praying in the Spirit, as we don't know how to pray as we should. Just be aware that He's got the whole world in His Right hand, and not distracted from listening to you as a friend: more than one women have seen Jesus holding something in His hand and listening to her, then finding out what it was He was holding in His hand... God bless you, He will keep you with His peace as wholeness no mater what doctors have to say.
