Will you serve the Lord in truth with all of your heart?

My brothers and sisters in Christ, there is but one way to serve the Lord, and that is in truth and with all of your heart. God has promised to do great things for us, if we do what is good and what is right. Far be it that He should lie. I have seen the great things that the Lord has done for me, and because I know how it feels when the hand of the Lord is against me, I will serve him in truth and with all of my heart. so that I could experience His goodness.
