Summary: Are we just followers, or true disciples, of Jesus? There is a difference! If we are a true disciple, then we have rewards in heaven. If we are just followers, we may not. Let us learn about the demands of discipleship.
It is possible to be a follower of Jesus without being a disciple; to be a camp follower without being a soldier of the king; to be a hanger-on in some great work without pulling one’s weight. Someone was talking to a great scholar about a younger man. He said, “So and so tells me that he was one of your students.” The scholar answered, “He may have attended my lectures, but he was not one of my students.” There is a world of difference between attending lectures and being a student. It is one of the supreme handicaps of the church that in the church there are so many distant followers of Jesus and so few real disciples.—William Barclay
In the world that we live in today, commitment is a rare commodity. Commitment means that you will cling to something and refuse to let go of if it, no matter the cost. Too often, though, in our soft and pampered lifestyles, we have no idea what real commitment means. We get too comfortable in our easy chairs with our remotes, when we are called to a mission that could cost us our lives. Have we REALLY calculated the cost it takes to be a disciple?
The word "count" literally means pebble. It is used in reference to a one-on-one count. “Well this tower is going to take 229,487 bricks. And it’s going to take 37,329 pieces of steel. Do we have that much on hand.” THAT is the kind of measuring that Jesus calls for when we are calculating what it will take to keep our commitments.
Can I finish the course: Can I follow Christ to the end? Can I be a faithful husband or wife for life? Am I willing to pay the price to godly parenting? If I am unwilling, I have no business making the commitment in the first place.—James MacDonald in Seven Things to Change Your Family
Once we have calculated the cost of commitment in following Christ, we are instructed to kill our old man, and crucify our old ways of living and thinking.
Not only are we to understand that we are kill off our old ways of living and thinking, but we are told how to do it. Paul told us in Romans 12 (quickview)  to “present our bodies a living sacrifice” and to “not be conformed to this world, but be ye transformed by the renewing of your minds.”
This all sounds well and good, but why is this so important?
A little hobby of mine is collecting old Coca-Cola memorabilia. One of my prized possessions is this old bottle from around 1910 to 1920. It was made at the Charleston Bottling Works in Charleston, WV.
Many of you will doubtlessly remember when soda came in a glass bottle like this, not in plastic bottles like today. When you bought just one, or a carton of bottles, you were required to pay a 10 cent deposit. Then when you brought the bottle back, you either got your deposit back, or it went toward the next carton of bottles.
