How can ten simple words be so powerful?

When you believe in Jesus Christ and surrender your life to him. You know whatever challenges life throws your way, God is with you and will give you his strength to endure.
Most of you know, I have been going through some medical issues but I claim this promise;“But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint” (Isa. 40:31).
Praise God. He is renewing my strength daily. Dependence on God is not a weakness it is the power and strength to allow God to work through us. As the word of God says.
“The LORD is my shepherd; I shall not want. He maketh me to lie down in green pastures: He leadeth me beside the still waters. He restoreth my soul: He leadeth me in the paths of righteousness for his name’s sake. Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; Thy rod and thy staff they comfort me. Thou preparest a table before me in the presence of mine enemies: Thou anointest my head with oil; my cup runneth over. Surely goodness and mercy shall follow me all the days of my life: And I will dwell in the house of the LORD for ever.”
