Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven. – Matthew 5:16

It is by such works that the mouths of gainsayers are to be stopped. One holy action is a better argument against blasphemers than a thousand eloquent discourses. You are our replies to sceptics-you who having been rescued from sin maintain a life of holiness. When they see the men that are healed, standing with Peter and John, they can say nothing against them. Oh, by your works confound gainsayers! These works, too, bring glory to God. “That they, seeing your good works may glorify your Father which is in heaven.” And these works also ensure peace to your own conscience, and have much to do with your close communion with God. “How can two walk together except they be agreed?” If ye walk contrary to Him He will walk contrary to you. Your sins will separate between you and your God, but the Holy Spirit, where He maintains holiness, maintains peace and communion in the soul. “If ye abide in Me, and My words abide in you, ye shall ask what ye will, and it shall be done unto you.” “If ye keep My commandments,” saith the Savior, “Ye shall abide in My love”-you shall abide in the conscious fellowship of that love, and in the enjoyment of it. May God help you, may God help you, for His name’s sake.

(Look ye here, ye who say you believe in Christ and are living in sin: what does this make of your boastings? Look you here, ye that say “I have only to believe by-and-by, and I may live as I like, and yet be saved.” Is it so? Is it so? “If the righteous scarcely be saved, where will the ungodly and the wicked appear?” …The salvation of Christ is not a salvation in sin, but a salvation from sin.) ~ C.H. Spurgeon
