“The LORD of hosts is with us; the God of Jacob is our fortress.” Psalm 46:11

Yesterday, I had the opportunity to preach for Reformation Sunday at Redeemer Presbyterian Church (PCA) here in Austin, Texas. We have four pastors at Redeemer, and since I am the only one who is “semi-retired” I usually preach once or twice a year. Instead, my main role at Redeemer is focused on teaching. I regularly instruct adults in our School of Discipleship classes on Sunday mornings. Beyond that, I am the director of Redeemer Theological Academy teaching college-level courses in Biblical studies, Systematic Theology, Church History, Apologetics, and Ministry. This suits me quite well, and I am grateful to focus my energies on teaching at this point in life. Nonetheless, below is an audio file of my most recent sermon. Also, you will find an introduction to the sermon and an outline of the text. I hope you enjoy it!

“The Lord is our Fortress” – Psalm 46:1-11

Introduction: The image of a “fortress” or “stronghold” in relation to the Lord shows up in many passages in the Old Testament (e.g. 2 Sam. 22:1-4; Ps. 9:9; 18:2; 31:3; 71:3; 91:2; 144:2; Prov. 18:10; Jer. 16:19). It is a portrait of strength, security, and safety for the people of God. Indeed, the Lord is the only one who could provide such protection in times of trouble. He is the one who created all things and also controls all things (Ps. 103:19). Essentially, this word-picture of a “fortress” and “stronghold” teaches us the doctrine of the sovereignty of God. In other words, we can believe that when everything in our world seems to be falling apart we can take comfort from the fact that all things are firmly under the control of the Lord. Even when misfortunes come our way, or when wickedness is exalted, we can be confident that “The Lord has made everything for its purpose, even the wicked for the day of trouble” (Prov. 16:4). This doesn’t mean that we never experience any difficulties and trials in life. It does mean, however, that God is in the midst of these difficulties and trials, and that he is able to bring good out of them (Rom. 8:28). Let us, then, go forward as those who trust in the sovereign rule of the Lord over all things in our own personal circumstances and in the tumultuous events of this world. Soli Deo Gloria!
Here is an outline of my sermon:
1. The Lord is our Refuge and Strength, (vs. 1-3)
2. The Lord is the Source of All Blessings, (vs. 4-5)
3. The Lord is the Ruler of the Nations, (vs. 6-9)
4. The Lord is the King of His Saints, (vs. 10-11)
