Is the Christian life confusing? Not really. Many religionists, seeking to justify themselves, and enslave others in their own perversions, make it seem very difficult and foreboding.
But really, what is important? Where does one start?
Three great Truths must be kept before you:
1) Jesus Christ is the end of your life. If you are to be a Christian, you must be in Him.
2) You cannot be in Christ, without being an active, faithful member of His visible Church, His Body (and Bride).
and 3) You cannot be a good churchman without putting the Lord's Day's church worship, and the principle of the Sabbath, into the very center of your entire existence.
This makes Christianity very practical. "Am I in God's good graces?," someone may ask. The answer: "Do you love Jesus? Do you hate your sin? Do you love what Christ loves? Are you faithful in the little things?"
See, understanding Christianity is not really all that difficult; and it is certainly not "rocket science."
