How does one give all things to God? There are those who would answer with a witty, christianese statement that simplifies the entire process. There are those who would quote a verse as though the verse in itself is the process. But if it were that easy, would Christ have prayed to God that his cup pass from him if that were at all possible? By cup, meaning his torture and eventual death on the cross.
What if the very depth of a person's soul and what they believe to be the greatest part of their existence is in jeapardy? Will a simplistic remark and/or bible verse set things right in a hurry? I think not.
The best answer I can come up with is that it's in the process, tears, begging, denial, anger, grief, and endangered hopes that we walk a path similar to the one of Christ, with a cross unique to our own life and situation. In the process, perhaps somehow we learn to stop begging for a different path and accept the cup which we are given and peacefully resign ourselves to whatever may come. I guess that's the best I can come up with for now.
