The most important lesson that I have learned is to trust God in every circumstance. Lots of times we go through different trials and following God's plan seems like it doesn't make any sense at all. God is always in control and he will never leave us.
And I will do everything that I can as long as I am President of the United States to remind the American people that we are one nation under God and we may call that God different names but we remain one nation.
