Today there are a lot of people saying that just believing in Jesus is enough to get you to heaven. Now, I believe that we are saved by faith alone; however, I also believe that true saving faith will be seen in the way we live our lives. The desires of those who are saved have been changed. They no longer hunger and thirst after the things of this world, but hunger for the holiness, righteousness, and purity of Christ Jesus.

Dr. Donald Whitney’s post “No Coasting into Christlikeness” clearly identifies what the Bible says about growing in godliness. Godliness is not an option for the true believer. Once we receive the Spirit of God our lives are eternally changed.

Whitney writes:

When it comes to discipline in the Christian life, many believers question its importance. Devotion to prayer declines into drudgery. The real-life usefulness of meditation on Scripture seems uncertain. The purpose of a discipline like fasting is a mystery. Why not leave spiritual discipline to those who seem to more disciplined by nature and let the rest of us “live by grace”?

First, we must understand what we shall become. The Bible says of God’s elect, “For those whom he foreknew he also predestined to be conformed to the image of his Son” (Romans 8:29). God’s eternal plan ensures that every Christian will ultimately conform to Christlikeness. We will be changed “when he appears” so that “we shall be like him” (1 John 3:2). If you are born again (John 3:3-8), this is you, Christian, as soon as “he appears.”

 So why talk about discipline? If God has predestined our conformity to Christlikeness, where does discipline fit in? Why not just coast into the promised Christlikeness and forget about discipline?

Although God will grant Christlikeness to us when Jesus returns, until then He intends for us to grow toward it. We aren’t merely to wait for holiness, we’re to pursue it. “Strive for peace with everyone,” we’re commanded in Hebrews 12:14, “and for the holiness without which no one will see the Lord.” Notice carefully what that says: without holiness—that is, Christlikeness; Godliness—no one will see the Lord, regardless of how many times they’ve been to church or how often they’ve engaged in religious activities or how spiritual they believe themselves to be.

 It’s crucial—crucial—to understand that it’s not our pursuit of holiness that qualifies us to see the Lord. Rather, we are qualified to see the Lord by the Lord, not by good things we do. We cannot produce enough righteousness to impress God and gain admittance into Heaven. Instead we can stand before God only in the righteousness that’s been earned by another, Jesus Christ. Only Jesus lived a life good enough to be accepted by God and worthy of entrance into Heaven. And He was able to do so because He was God in the flesh. Living a perfect life qualified Him to be a sacrifice that the Father would accept on behalf of others who by sin had disqualified themselves from Heaven and a relationship with God. As proof of God’s acceptance of Jesus’ life and sacrifice, God raised Him from the dead.

In other words, Jesus lived a perfectly righteous life in complete obedience to the commands of God, and He did so in order to give the credit for all that obedience and righteousness to those who had not kept all of God’s law, and He died for them on a Roman cross in order to receive the punishment they deserved for all their sins against God’s law.

 As a result, all who come to God trusting in the person and work of Jesus to make them right with God are given the Holy Spirit (Ephesians 1:13-14). The presence of the Holy Spirit causes all those in whom He resides to have new holy hungers they didn’t have before. They hunger, for example, for the holy word of God—the Bible—that they used to find boring or irrelevant. They have new holy longings, such as the longing to live in a body without sin and to have a mind no longer tempted by sin. They yearn to live in a holy and perfect world with holy and perfect people, and to see at last the One the angels perpetually praise as “Holy, holy, holy” (Revelation 4:8). These are some of the holy heartbeats in all those in whom the Holy Spirit resides.

Consequently, when the Holy Spirit indwells someone, that person begins to prize and pursue holiness. Thus, as we have seen in Hebrews 12:14, anyone who is not striving for holiness will not see the Lord. And the reason they will not see the Lord in eternity is because they do not know the Lord now, for those who know Him are given His Holy Spirit, and all those indwelled by the Holy Spirit are compelled to pursue holiness.

 And so, the urgent question every Christian should ask is, “How then shall I pursue holiness, the holiness without which I will not see the Lord? How can I become more like Jesus Christ?”

We find a clear answer in 1 Timothy 4:7: “Discipline yourself for the purpose of godliness” (NASB). In other words, if your purpose is Godliness—and godliness is your purpose if you are indwelled by the Holy Spirit, for He makes godliness your purpose—then how do you pursue that purpose? According to this verse, you “Discipline yourself for the purpose of godliness.”

 This verse is the theme for Spiritual Disciplines for the Christian Life. In it I attempt to unpack the meaning of 1 Timothy 4:7 and apply it, chapter-by-chapter, in practical ways. I will refer to the scriptural ways Christians discipline themselves in obedience to this verse as the Spiritual Disciplines. I maintain there that the only road to Christian maturity and Godliness (a biblical term synonymous with Christlikeness and holiness) passes through the practice of the Spiritual Disciplines. I emphasize that Godliness is the goal of the Disciplines, and when we remember this, the Spiritual Disciplines become a delight instead of drudgery.
