God is never at a loss because He cannot find someone to cooperate with Him in carrying out His plan. He so moves in the hearts of people - either Christians or non Christians, it makes no difference - that they willingly, of their own free will carry out His plans.
All pain we experience is intended to move us closer to the goal of being holy as He is holy.
Trials always change our relationship with God. Either they drive us to Him, or they drive us away from Him. The extent of our fear of Him and our awareness of His love for us determine in which direction we will move.
