There are two main parts to the instruction from Scripture on the Christian life that follow. The first is that a love of righteousness—to which we are not naturally prone—must be implanted and poured into our hearts. The second is that we need some model that will keep us from losing our way in our pursuit of righteousness. Scripture contains many arguments to encourage us on the path of righteousness.
To begin with, what better foundation can Scripture give for the pursuit of righteousness than to tell us we should be holy because God Himself is holy? Moreover, when we were scattered and wandering like sheep, lost in the maze of the world, God found us and gathered us to Himself. When we contemplate this relationship between ourselves and God, let us remember that holiness is the bond of our union with Him. Not, of course, because we enter into fellowship with Him by the merit of our own holiness. Rather, we first of all, cling to Him, and then, having received His holiness, we follow wherever He calls us. For it is characteristic of His glory that He has no fellowship with sin and impurity. Holiness is the goal of our calling. Therefore we must consistently set our sights upon holiness if we would rightly respond to God’s calling. To what purpose did God pull us out of the wickedness and pollution of this world—wickedness and pollution in which we were submerged—if we allow ourselves to wallow in such wickedness and pollution for the rest of our lives?
Furthermore, if we count ourselves among God’s people, Scripture tells us to live as citizens of the holy city of Jerusalem, which He has consecrated to Himself.
For here we have no lasting city, but we seek the city that is to come. (Hebrews 13:14)
It’s shameful that the citizens of the holy city should pollute it by their impurity. Thus, we read that there will be a dwelling place in God’s tabernacle for those who walk blamelessly and pursue righteousness. It’s not right that the sanctuary in which God dwells should resemble a filthy stable.
To prompt us toward righteousness more effectively, Scripture tells us that God the Father, who has reconciled us to Himself in His Anointed One, Jesus Christ, has given us in Christ a model to which we should conform our lives. You will not find a better model in the philosophers—in whom many expect to find the only correct and orderly treatment of moral philosophy. They, while doing their best to encourage us to be virtuous, have nothing to say except that we should live “according to nature.” Scripture, however, draws its encouragement from the true fountain. It teaches us to contemplate our lives in relation to God, our Author, to whom we are bound. And, having taught us that we have fallen from the true state and condition of our original creation, Scripture adds that Christ, through whom we have been restored to favor with God, is set before us as a model whose form and beauty should be reflected in our own lives. What could be more effective than this? Indeed, what more is needed than this? We have been adopted by the Lord as children with this understanding—that in our lives we should mirror Christ who is the bond of our adoption. And truly, unless we are devoted—even addicted—to righteousness, we will faithlessly abandon our Creator and disown Him as our Savior.
What I am saying is this: Let us fix our eyes on the goal and sole object of our pursuit. Let that goal, toward which we must strive and contend, be established from the beginning. After all, it’s not right to barter with God regarding what we will and won’t undertake from those things He has prescribed for us in His Word. God always commends—as of utmost importance—integrity as the principal part of His worship.
And as for you, if you will walk before me, as David your father walked, with integrity of heart and uprightness, doing according to all that I have commanded you, and keeping my statutes and my rules, then I will establish your royal throne over Israel forever, as I promised David your father, saying, “You shall not lack a man on the throne of Israel. (1 Kings 9:4–5)
And by the word integrity, He means sincere simplicity of heart, free from pretense and deceit, which is the opposite of duplicity of heart. In other words, right living has a spiritual basis where the inner affection of the soul is sincerely devoted to God for the nurture of holiness and righteousness.
Of course, none of us is capable of running swiftly on the right course while we remain in the earthly confinement of our bodies. Indeed, most of us are so oppressed with weakness that we make little progress—staggering, limping, and crawling on the ground. But let us move forward according to the measure of our resources and pursue the path we have begun to walk. None of us will move forward with so little success that we will not make some daily progress in the way. Therefore, let us keep trying so that we might continually make some gains in the way of the Lord, and neither let us despair over how small our successes are. For however much our successes fall short of our desire, our efforts aren’t in vain when we are farther along today than yesterday. So let us fix our eyes on the goal with sincerity and simplicity, aspiring to that end—neither foolishly congratulating ourselves, nor excusing our evil deeds. Let us press on with continual striving toward that goal so that we might surpass ourselves—until we have finally arrived at perfection itself. This, indeed, is what we follow after and pursue all our lives, but we will only possess it when we have escaped the weakness of the flesh and have been received into His perfect fellowship.
