“The Lord lives, and blessed be my rock, and exalted be the God of my salvation— the God who gave me vengeance and subdued peoples under me, who rescued me from my enemies; yes, you exalted me above those who rose against me; you delivered me from the man of violence. For this I will praise you, O Lord, among the nations, and sing to your name.” (Psalm 18:46–49, ESV)

The other day I read a social media post from a Christian who attacked those that use the Bible to teach “piety” or “moralism” in sermons instead of simply pointing to Jesus’ saving work on the cross of Calvary as an act of worship. In other words, the Bible is all about what Christ has done and not about what Christians should do. Another way it is often stated is that we should teach the indicatives of the Bible (what God has done through Christ) and not so much the imperatives (what we should do as Christians). This has led some who teach this view into a dreadful form of antinomianism that gives way to a shipwrecked life.

I understand the failure of some preaching that twists the Bible into a life-manual for fixing our problems. These types of churches and the sermons they produce seem to be a religiously themed self-help motivational courses. Theology and doctrine are downplayed, and God is only taught in the sense that He is the power that you need to tap into to get the life you want. That is abuse of the Bible and the God of the Bible, and make no mistake, this is wrong.

But it is also wrong to say that the Bible is only about what God has done for us at the cross. I only need to point to the book of Ephesians to show that in a letter of six chapters, the first three chapters are dedicated to proclaiming the glorious theology of salvation through Jesus Christ, BUT the second three chapters deal with the implications of that change in the life of a person, including several imperatives. In other words, the Bible is not simply about the indicatives and what God has done for us, but flowing out of the indicatives are some very important imperatives that can only truly be accomplished in a God-pleasing way through the active role of the Holy Spirit in the life of a regenerate person. Christians are called to obey God by the power of the Holy Spirit.

I say all of this because in my reading through Psalm 18 this morning I was once again enamored with the radical change that dwelling upon the Scriptures has in the heart and mind of the child of God. This psalm has a heading, also called a superscription that tells the reader the context in which it was written. In the case of Psalm 18, it was written when David was being hotly pursued by his enemies, including Saul. Knowing how close to being caught and murdered he was, David recalls the terrifying place he was in and how he called out to the Lord desperately, and the Lord heard his cries. It is a wonderful psalm that pictures God rising from His heavenly throne and ascending upon the back of an angel to save His child David with the vengeance of a warrior.

But is this passage simply for me to read and appreciate? Does it not instruct me, and those that I would teach it to that our God loves His own, and that He is moved by our cries to come to our aid and save us? You see, this passage is meant to do more than describe David’s personal experiences. It was put into a song so that the people of Israel would praise their God who saves–but who saves more than just the king. He is the God who saves His people, from the greatest to the least in the kingdom. I can apply this text to myself and others by calling Christians to cry out in prayer in their times of need. God answers prayer! We must be people of prayer!

This is the glory of the Bible. We do not need to choose between what God has done and what we should do in response. The two go together and shouldn’t be separated. And this psalm is a wonderful place to go to strengthen weakened hands when the battle has become too much and the broken and weary need to be reminded that God hears our cries. So, when you study the Bible, make sure you not only teach it accurately, but also make sure you apply the text to the lives of those who need to have their weak hands strengthened.
