Heart Prep for Sunday, April 7th

I hope that you had a blessed Easter holiday! This week, we come to Luke 8:18-35. In this passage, we find that John the Baptist has sent messengers to confirm that Jesus is the Messiah. Now, this struck me as somewhat odd since John knows deep down in his soul that Jesus is the one he's been waiting for. But then I realized that I often do exactly what John did whenever m...

A quick reminder that there is an open house/reception at the Rist House tomorrow (Friday, March 15) from 4-6:30pm, with a devotional and prayer time at 5:30pm. I'd encourage you to spend some time with your church family as we grieve together the passing of Iris Dillard. And we grieve not so much for her death, because she is alive and rejoicing with her savior, but for o...

Have you ever had the wonder of something fade in your mind? The first time you kissed your spouse when you were dating was (hopefully) a wonderous experience. But after locking lips for the next 5-10 years, the thrill of the kiss wears off.In some cases, it can be easy to take the wonderful almost for granted. There's a phrase for this: Familiarity breeds contempt. And ou...

As Christmas Day marches toward us, I hope that you've gotten everything squared away so that you can simply enjoy the holiday. From the pastors, staff, elders, and deacons, we wish you a safe and happy Christmas! Just a quick reminder that we will be having Sunday School and worship as usual this Sunday, even though it is Christmas Eve. We will also be having a Christmas ...

It's the Thanksgiving holiday, and I can't help but be thankful for Potomac Hills Presbyterian Church. I am so grateful for all of you. Your care and ministry to my family over the years has been amazing. You've showed us grace and love, even when we didn't deserve it. You've forgiven us of our sins against you, and you've pointed us to Jesus over and over again. Thank you...

While we have been in a season of crises, there have been encouraging signs that perhaps this season is passing. Keep praying for Isaiah and Kelley as they continue to walk through healing and the ups and downs that come with that. Also be praying for Dr. Dave. He's off on study leave this week, and will be visiting family. As we continue in our series on the Timothy's, t...

After a few weeks off for Easter and pastors being out of town, we're back in the book of Job with another length chunk of text. We've got 6 chapters this week: 32-37. Again, I encourage you to read the passage ahead of Sunday worship. I won't have the chance to read all of it during the sermon. I also encourage you to flip back a few chapters, read some subheadings, and g...

We have another chunk of Job to work through this week as we come to Job 20-24. By this point, you can probably guess what Job's friends and Job will say. Something along the lines of wicked people get whacked, you're wicked Job, and repent Job from the friends. Then for Job, something along the lines of this isn't fair, the wicked prosper while the righteous don't, and my...

We rarely set out to have an argument, a shouting match, a dialogue that brings hard feelings and strong language. We usually have good intentions going in, but things seem to devolve so easily as frustrations mount and inflammatory statements are not met with grace. Such it is with Job's friends. They've come ostensibly to comfort Job. And we know that they're doing a ter...

Another week, another sermon. Another week, another cycle of waking, working, eating, and sleeping. It's all pretty repetitive, and I'm going to bet that our sermons in Job will end up sounding repetitive. And that's somewhat by design. The writer of Job understands that both Job and readers of this book (That's us!) are dense of heart. We need to hear the same stuff over ...

Heart Prep for Christmas Day

Christmas is upon us, and Advent is drawing to a close. And as we finish up Colossians chapter 1 by looking at verses 24-29, there is this sense that the wait is finally coming to an end. Christmas Day is almost here. But our wait for Christ to come is obviously different from the wait that Mary and Joseph endured so long ago. Now, we know that Christ has come, and that He...

It's hard to believe that Advent is right around the corner. I really encourage you to spend some time this weekend meditating on Advent and to write a devotional to share with the rest of the church family.

Before we hop into talking about how to prepare for the sermon this week, I want to take the time to bring something important to your attention.

As we prepare for worship this Sunday, I think that it's appropriate for us to take some time to honor our brother Jerry German. In the several conversations that I've had with Jill this week, she has gushed over Jerry's faith, faithfulness, care, and love for her over 56 years of marriage. What a wonderful testimony of God's goodness and grace in Jerry and to Jill! Please...

We have come at long last to the end of Deuteronomy. As with last week, we have 4 chapters to cover this Sunday, Deuteronomy 31-34. In these chapters, we get the plan to transition leadership to Joshua in chapter 31, the Song of Moses in chapter 32, blessings on each of the tribes in chapter 33, and Moses's death in chapter 34. I encourage you to spend time reading it sinc...

What to do about Deuteronomy 24:8-25:4? The range of topics across these 8 laws is quite broad.

I encourage you to read the passage for this Sunday ahead of time and meditate on the need...

What would happen if someone told you that you had to worship in a certain place, at a certain time, and in a certain way? I think we'd all be up in arms about it. We'd hope that we would say that we must obey the Lord first, and then man. But what if it were God telling you where, when, and how you'd worship? Would you still chafe at the command? As Americans living in th...

It occurs to me that Super Bowl Sunday is a day filled with shifting allegiances.

This Sunday is Reformation Day! It's also the Sunday that we come to the Lord's Table, and it's also the day of the Fall Festival.

The pursuit of glory is often at the core of our motivations. Even if we don't dream of making it big and becoming a celebrity, we still pursue glory. Maybe it's the praise of your co-workers that you covet. Maybe it's the praise of your parents that you crave. Maybe it's a simple recognition that you are capable, competent, and mature. We often see glory and recognition a...

As we continue in our series in Joshua this week, we're going to get a serious case of dj vu. Just as we saw massive armies being completely wrecked by the Lord and Joshua in chapter 10, we're going to see much of the same this week.

How many times have we sinned against the Lord and wondered if we had finally gone too far? That's not the way the Gospel and grace work, but it's still a thought that creeps in to strike at our confidence in Christ. And it feels right and real because it's half-true. It takes a good look at sin, and it correctly judges that sin is a big deal. But it forgets that grace doe...

How many times do we find ourselves laboring through the mundane preparations of life under our own strength?

In preaching, some of the best advice is to keep the main point of the passage as the main point of the sermon. This is great advice because there so such a depth to the Scriptures.

We’ve made it. After 38 weeks, we’ve come to the end of our series in Jeremiah. Let me tell you that this has been a challenging book for the pastors and elders to preach on.

That interpretation would even have an appearance of truth since James empha...
