"Tribulations" brings thoughts of trouble, anxiety, fear, and doubt. However, Paul writes in Romans 5:3-5 that those who have peace with God and access to Him
. . . glory in tribulations, knowing that tribulation produces perseverance; and perseverance, character; and character, hope. Now hope does not disappoint, because the love of God has been poured out in our hearts by the Holy Spirit which was given to us.
This peace is not a kind of secular contentment that men can find by lowering their standards and expectations. It is both a gift from God to those reconciled to Him through Jesus Christ and a product of the Holy Spirit in us as we grow in a continuing, trustful relationship through the daily affairs of our life.
The Christian's outlook on life can be entirely different from those in the world, untroubled by the calamity they see all around them. This does not mean that the Christian's peace is a sort of magic or that he ignores the seriousness of the situation. Nor does it mean that the Christian achieves this wonderful quality instantly or that it is always constant. However, it is always available through faith because he has access to the Sovereign, Almighty God. He always has everything under control and is filled with love and wisdom that He is willing to use for our benefit.
