Our God is a treasure to be enjoyed, worshiped, and obeyed.
The basis for biblical interpretation begins with Jesus.
The book of Psalms shows us not only how to do to right theology, but also how good theology should lead us to worship and right living before the Lord.
Listening well and taking good notes during the sermon is a means to an end. That end is our growth in Christ and understanding of the Bible.
The whole Bible is for the entire Christian because the entire Bible has a unified message in the gospel of the Lord Jesus.
