1. Get more sleep.
The Sunday service is not for sleeping; the night before is. This requires planning, especially for young people, who like to use Saturday night as an opportunity to stay up as late as possible.
2. Sit closer to the front.
Almost without exception, the best listeners are in front. Whenever I am not preaching and I'm sitting in the pew when I visit a church or attending conferences, I make it a point to sit no further back than the second or third pew. Sitting close to the front enables me to listen and to better experience the whole worship service.
3. Minimize distractions.
If you must, find a better place to sit. If your children are the problem, “divide and conquer” by asking a relative or friend to sit with you. And don’t permit the Sunday shuffle to the restroom.
4. Use your Bibles.
I'm amazed at how many Christians show up to church without a Bible. It is difficult to follow the pastor’s line of thought without seeing the Bible text before you.
5. Take Notes.
Taking notes helps to keep your mind on the message as you listen for key words or thoughts to write down. A word of caution here though: Don't spend so much time writing that you miss a portion of the message. Key words or thoughts are enough to help you remember.
6. Discuss the Message with your family after the worship service.
While you are riding home or to your favorite restaurant, or while you are around the dinner table, make it a practice to briefly discuss the message with your spouse and children. Knowing you will be doing this will keep you accountable. Ask questions like, what one point or comment impacted you the most? How can we apply it to our lives this week?
When you sleep through a sermon you miss what may possibly be your best opportunity to hear from God that whole week. Take these steps that you don't miss hearing from God.
