Attitude is everything.
Above all else, guard your heart, for it is the wellspring of life, Proverbs 4:23.
The enemy wants to hijack my heart, making me expect and anticipate bad things. This world is evil, but the devil wants me to believe that I face this evil world alone and unprotected. Somehow, I fall for this trick over and over.
Jesus has promised us that he is with us always, even to the end of the age. Paul tells Timothy that God has not given us a spirit of fear, but of power, of love and of self-discipline.
It is up to me, with the help of God, to guard my heart, my attitude. When I believe that God has good things for me, even today, I trust him even when the going gets hard.
No trouble has ever come on me that God has not redeemed, either in the short run or the long run. I can trust him with my schedule, my conversations, my safety, my future. I'm not an orphan. I have a Father, and he walks with me through all the shadows of death.
