"Do not merely listen to the word, and so deceive yourselves. Do what it says..." So what are we supposed to do? First, intently look at God's Word. Try to figure out what it is saying. What is God saying to me? Sometimes we read God's Word, and we never actually know what the verses are saying. Take the time to figure out how to apply the verses. Then once we have learned what God is saying to us...keep listening...and keep obeying what we learned.
Otherwise, the Bible says we are like the person who looks in the mirror and forgets what they saw. That could be a little scary on some days. Several years ago my kids were playing with stickers, and they put stickers all over me. We were home for the morning, and I forgot about the stickers. There was a package dropped off, and I went to the door and signed for it. After I closed the door, I realized I was still covered with stickers. We don't want to be walking around looking like a mess because we don't take the time we should to really get into God's Word and apply it.
