If you know these things, blessed are you if you do them.
Knowledge is very important for Christian living. I'm old enough to remember that's it used to be common for churches to have someone tasked with what was known as "Christian Education". I remember quizzes in Sunday School that we studied for during the week, and Bible "class" in Christian School. This of course carried right through for me to full-fledged academic fruition with a seminary education complete with a Master's thesis and verbal examination on all aspects of biblical content and theological understanding.
Knowledge is important and sound doctrine organized in a theological format is vital. I'll always commit to that as a necessity. But we must not forget that Jesus expects knowledge to equip us to DO WHAT WE KNOW. Christian faith is a lifestyle. Following Jesus is active. We don't do good things to gain salvation, but we must do good things as an outflow of what we know and believe. God has decreed that the church know, believe, and proclaim the gospel actively both in her message and in her methods and good works. That is how Jesus redeems the world.
Jesus told His disciples that the blessing was in the doing. Oh how we need to never be content in knowledge of the truth alone! Oh Lord, make us doers of Your Word and not hearers only!
