While I'm not into discussing suicide right now, I do believe that there are Christians who end their lives before their time (as ordained of God, that is.)

Yes, I agree they feel the load and feel they cannot handle it.
I wonder if it is because of the lack of touch with God? Depression causes loss of faith and loss of contact like that...but then one would wonder at that time why the angels or God Himself doesn't step in and help? But then, we do have freewill...

...and to die is gain for one is with Christ then....
