"For everything that was written in the past was written to teach us, so that through endurance and the encouragement of the Scriptures we might have hope."
What happens to people when they lose hope? They give up. They quit. Hope and perseverance go together. Hope is a future promise that keeps us going. It is the carrot before the donkey. Hope knows that there is a goal, and that the goal is worth pursuing, even through hardship and difficulty. If we don't have hope, we won't have perseverance.
Paul writes in Romans 15 is that everything in the Scripture—by which he means what we call the Old Testament—was written to instruct us in the Christian hope. Throughout the Old Testament we see God's faithfulness in spite of man's sin. We see the saints going through times of suffering and discouragement. We see the saints exiled to the wilderness, with no apparent future. But we also see that in time, God brings them back for greater service than before. The kingdom of God never shrinks; it may flow underground for a season, but it always emerges mightier than before. God is not going to be the loser in history!
Thus, with the encouragements of the Scripture before us (Old and New Testaments), we should have hope. And following God's example, we should encourage one another. Paul writes in Romans 15:5–6 that we encourage one another when we live in unity, without being at each others' throats, and that a fundamental expression of that unity is worship. When we stand together to sing God's praises in the psalms and great hymns and prayers of the church, we encourage one another. The man who comes to worship downcast and beaten may emerge with new hope simply because of the unity of worship he has experienced.
Paul says that God gives endurance and encouragement (verse 5). It is not just the history of redemption as recorded in the Bible that gives us encouragement. It is not just the continuing history of the church, which indeed shows growth over 2,000 years, that gives encouragement. And it is not just the fellowship of other saints, in life and in praise, that gives encouragement. But it is primarily God Himself who gives us encouragement. If we lack endurance and hope, we need to learn more about the attributes and intentions of God; for the more we know Him, the more encouraged we will be.
Coram Deo
Psalms are a great source of encouragement, because (a) they meet us where we are, in the midst of difficulty and conflict, (b) they remind us of what God has done, and (c) they bring us face to face with God in prayer. Let's get the psalms back into our worship and our private devotions.
