The believer must choose to operate in what the word of God has to say. This takes humility. Humility being the virtue needed to honor the word of God. Trusting God will definitely come through for you if you let it. Apart from trust in God you will surely allow the inevitable adversities in life to be converted to inner stress of the soul.
Stress is simply reaction as the means of dealing with pressure.
Many react and dwell in their emotions as a form of dealing with pressure. This invites stress into the soul and stress prevents metabolized doctrine from functioning. Spiritual strength is needed in handling adversity and preventing stress in the soul. If we want to take part in the victory of Jesus Christ we must walk in obedience to God's plan not only on sunny days, but most of all on very dark and dismal days. Satan takes pleasure in broken relationships marked by betrayal, abuse, bullying, apathy, jealousy, and emotional bondage.
