As Christians we learn to put our trust and faith in our God, not in our own ability. When we find ourselves discouraged typically the source is found in a lack of trust in our Heavenly Father. God does indeed allow troubles for us, for our benefit even. These troubles force us to make a decision, a very conscious decision. To whom will we go in our times of trouble. Do we go to friends for comfort, or family, or posessions, or money, or food, or pleasure?
This is where the Christian learns to overcome! We overcome our troubles of heart, through our testimony. We find true lasting comfort in the remembrance of God in our lives: what He has done for us in our personal history and most of all, what was done on the cross of Calvary. It is in that place of remembrance our soul finds rest. We are set free from a troubled heart, when we lay our burdened heart at the cross of the Christ.
Revelation speaks of the ones who overcame the great tribulation, saying, "that they overcame by the word of their testimony and by the blood of the Lamb..." Revelation 12:11 This is our path to victory and we are daily learning to overcome every kind of trial and trouble of heart in this way. Without our testimony and without the blood of Christ over us, we will fail in any attempt to overcome evil in its many forms. May God grant you strength to overcome sin today!
