How does knowing the future is in God's hands help you face the future?
If a person believes that their future is in God’s hands, they are more likely to be able to face that future because they can be confident that there is a plan for their future. They will be more likely to feel that there is a reason for what is happening to them.
People often say things to the effect that “God does not give you things that he knows you can’t handle.” This is fairly reflective of how knowing your future is in God’s hands can be helpful to you. Imagine that you are faced with something that seems like a really terrible thing. Perhaps you have lost your job, or have a terrible accident, or lose a spouse. If you know that your future is in God’s hands, these things become somewhat more tolerable. You can believe that God has a plan for you and you can understand that what is happening to you is all part of a plan made for you by someone who knows what is best for you and who truly cares about you. You know that you will not suffer these problems in vain.
Thus, a person who believes that their future is in God’s hands can be much more confident and at peace than someone who does not.
