The Power of a Holy Life (Part 2) By John MacArthur

Holy Living Makes the Gospel Attractive
Paul states his third reason for holy living in Titus 2:10, “That they will adorn the doctrine of God our Savior in every respect.” “Adorn” is from the Greek word kosmeō and refers to making something beautiful.
What is our primary message to this world about God? Do we want the world to know that God is omnipotent? Omniscient? Omnipresent? Immutable? Sovereign? Eternal? The Creator and the Sustainer of the universe? Yes, we do. But by far the main attribute of God we want the unsaved to understand is that He is a Savior.
How will we ever make the good news about God as Savior beautiful in every respect if we don’t look like we’ve been saved? When we live in obedience to God, that in itself will be a testimony against wrong. When those around us see us helping rather than exploiting, hear us talking with purity instead of profanity, and observe us speaking truthfully rather than deceitfully, our example will itself be a rebuke of selfishness, unwholesome talk, and falsehood. Simply refusing to participate in a dishonest business or social practice will sometimes be such a strong rebuke that it costs us our job or friendship. Dishonesty is terribly uncomfortable in the presence of honesty, even when there is no verbal or other direct opposition.
Often, of course, open rebuke is necessary. Silent testimony will go only so far. Failure to speak out against and to oppose evil things in practical ways is a failure to obey God. Believers are to expose them in whatever legitimate, biblical ways are necessary.
Unfortunately, many Christians are barely able to keep their own spiritual and moral houses in order. Thus they lack the discernment, inclination, or power to confront evil in the church or in society at large. That’s why it is imperative that we be so mature in biblical truth, and in obedience, holiness, and love, that the natural course of our lives will be to expose, rebuke, and offer remedy for every kind of evil.
Making salvation attractive is a high calling, and we will fail in that endeavor unless we can demonstrate that we have indeed been delivered from sin. Rebuking sin in others without an accompanying lifestyle of righteousness is the greatest hypocrisy. But lives characterized by purity, power, and joy reflect the order, beauty, and power of a saving God. When we make salvation beautiful, we make God attractive.
To convince a man God can save, I need to show him a man He saved. To convince a man that God can give hope, I need to show him a man with hope. To convince a man that God can give peace, joy, and love, I need to show him a man with peace, joy, and love. To convince a man that God can give complete, total, and utter satisfaction, I need to show him a satisfied man. When the world sees people who are holy, righteous, peaceful, joyful, and fulfilled, they see the evidence of God’s transforming power.
At stake is the eternal destiny of unredeemed souls. Christians who are unholy lead unbelievers to slander God; those who are holy lead them to glorify God. The central issue in evangelism is holy living. A powerful church is not built on its strategy, but on the virtue and holiness of its people. What we believe is linked to how we live, and how we live is directly linked to the effectiveness of our gospel proclamation. So, Christian, it’s imperative that you be “blameless and innocent, children of God above reproach in the midst of a crooked and perverse generation, among whom you appear as lights in the world” (Philippians 2:15).
