Rule your own spirit. How? Jesus Christ: the author and finisher of our faith told us how. When He was hungry and thirsty, though he had the power to turn stone to bread but did not; Because he would rather obey the word of God and do His will. For publicity, Jesus could have jumped down from the pinnacle of the temple, he declined to tempt God but rather obey the word of God. And Like you and me, Jesus was tempted to trade off his Spirit for the glory of this vain world. He overcome the temptation by saying “… Away with you, Satan! For it is written, you shall worship the LORD your God, and Him only you shall serve.” Matthew 4:10
Psalm 27:1 “The LORD is my light and my salvation; whom shall I fear? the LORD is the strength of my life; of whom shall I be afraid.” This is not a wishful thinking or mere confession to boost your faith; but a declaration based on the knowledge of God – who is The Light, and the source and power of divine illumination. King David who wrote this song, had once; without a weapon killed a lion and challenged a well-equipped army with a sling. He obviously knew what he was talking about. During good and bad times, Experiential knowledge makes a lot of difference. David was literarily saying; I know the LORD is my light. He is the source of strength and salvation needed for victory over adversity, and for protection in times of peace.
