Fearing and Following God

A Sermon on Ecclesiastes 12:13–14:

The end of the matter; all has been heard. Fear God and keep his commandments, for this is the whole duty of man. For God will bring every deed into judgment, with every secret thing, whether good or evil.


DeRouchie gave this message at Bethlehem College & Seminary chapel on 31 January 2018 in order to kick-off a semester-long focus on Wise Living.

Far as the Curse Is Found

A Prayer for the Unengaged

O Christ, we declare this day that apart from you we can do nothing (John 15:5) but that with you all things are possible (Mark 10:27). You are stronger than the evil power that is working in all 195 countries of the world. And from the 44,000,000 in Argentina to the 57,000 in Greenland, from the coast of Senegal to the shores of Fiji, you are moving, calling, saving, shaping a community cleaving to you from every tribe and language and people and nation (Revelation 5:9). For 2,000 years you, the reigning God, have been saving and satisfying believing sinners through Christ’s life, death, and resurrection. Today there remains some 1,200 people groups dwelling in deep darkness with little to no engagement from those who claim they treasure Christ, yet the sovereign Savior came to slay the serpent far as the curse is found. read more…

Is Masturbation Okay?

Sexual intimacy within marriage is a beautiful gift from God. It’s an outlet for play and passion, and it nurtures closeness with your spouse, supplying a unique context for giving and receiving love. As a father, I long for my children to enjoy the bond of marriage without the baggage of past sexual sin, yet I know full well how rarely people maintain purity.

Glorify God in Your Body

Many medical professionals treat masturbation as a natural part of human development, and some church leaders have attempted to supply practical and theological reasons to masturbate. However, I do not believe this approach pleases God, and I have seen the devastation that such a practice brings to both singles and marrieds alike. My focus here is to clarify biblically why engaging in such activity outside the marriage bed is sinful and should therefore be avoided. Elsewhere I have expanded on my arguments. read more…

A Theologian of the Cross

If anyone’s will is to do God’s will, he will know whether the teaching is from God or whether I am speaking on my own authority. The one who speaks on his own authority seeks his own glory; but the one who seeks the glory of him who sent him is true, and in him there is no falsehood. (John 7:17–18)


For since, in the wisdom of God, the world did not know God through wisdom, it pleased God through the folly of what we preach to save those who believe. For Jews demand signs and Greeks seek wisdom, but we preach Christ crucified, a stumbling block to Jews and folly to Gentiles, but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God. For the foolishness of God is wiser than men, and the weakness of God is stronger than men. (1 Corinthians 1:21–25)


But whoever would be great among you must be your servant, and whoever would be first among you must be your slave, even as the Son of Man came not to be served but to serve, and to give his life as a ransom for many. (Matthew 26:26–28)

As a servant of Jesus Christ and an elder of his church and a trainer of his future under-shepherds, I long that my ministry and teaching glorify God. To do so, I must ever live out the testimony of John the Baptist regarding Christ, “He must increase, but I must decrease” (John 3:30). I must also celebrate God’s purposes to save the sinful, exult the humble, and supply triumph only through tribulation. “If anyone would come after me, let him deny himself and take up his cross and follow me. For whoever would save his life will lose it, but whoever loses his life for my sake will find it” (Matthew 16:24). Martin Luther carried this same resolve, and I celebrate that the Reformation fires he sparked continue to blaze in this world. read more…

A Prayer for the Unengaged

Our Father, you are in heaven yet you see and oversee everything on earth. From Afghanistan to Zimbabwe and the Bahamas to Yemen your common grace this dawn is allowing the light and warmth of the sun to rise on some 1,200 people groups who are still dwelling in spiritual darkness, completely unengaged with the gospel. At present, all of them are ungodly and unrighteous, suppressing the truth and neither honoring you nor thanking you as God. They have eyes, but have never seen your beauty. They have ears, but have never heard of that through Christ they can be saved. They are sexually immoral, idolaters, adulterers, practicers of homosexuality, thieves, greedy, drunkards, revilers, and swindlers, and right now none of them will inherit the kingdom of God (1 Cor 6:9–10). Their rebellion has made them your enemies and placed them under your wrath (John 3:36). They continue to love darkness more than light (3:19), and only bad news and hopelessness shape their existence. There is no fear of God before their eyes (Rom 3:18). Yet such were some of us. But we were washed, we were sanctified, we were justified in the name of the Lord Jesus Christ and by the Spirit of our God (1 Cor 6:11). read more…

For Our Instruction: Jesus’ Bible as Christian Scripture

In celebration of the 500th anniversary of the inauguration of the Protestant Reformation, Bethlehem College & Seminary recently had a conference focused on biblical interpretation titled Eureka! Discovering Gold in God’s Word. Drs. John Piper, Andy Naselli, and myself all presented messages related to our three recent books. My message, related to my How to Understand and Apply the Old Testament: Twelve Steps from Exegesis to Theology, argued (1) that the Old Testament is Christian Scripture, (2) that God originally gave the Old Testament to instruction Christians, (3) that the Old Testament authors had some sense that their words would be more meaningful for those living this side of the cross than for those living before it, and (4) that Jesus is supplies both needed light and lens for properly grasping the Old Testament’s message, enlivening us to read the Old Testament and to receive what is there (light) and guiding us to know how to read it in a way that ultimately points to him (lens).  read more…

The Greatest Wonder of the World

A Prayer of Praise

You alone are exalted higher than the sky. The greatest people and the greatest nations are like drops in a bucket that is carried along by you and you alone. The Milky Way galaxy has 100 billion stars, and there are 10 trillion galaxies of equal size; yet you know every star by name. Every blade of grass in the prairies, every needle in the pine forests of the West, every piece of sand on the beaches of the Caribbean and south Pacific, you know their number, and we stand in awe of you. read more…
