This is the practical application of seeking those things which are above. In effect what Paul is saying is that, if we are seeking those things which are above, the resources to overcome these things will be here. They will be part of us, because God responds to such as are truly seeking after Him.
Now, be patient. Our relationship with God is not magic. It takes work, does it not? And if any of you have any of these problems, you understand that you really have to hold a tight rein on yourself to keep yourself from doing these things that Paul says to "put off." They are so deeply ingrained within us that they want to break out, all by themselves. That is why Paul wrote that in Romans 7. "The things that I do not want to do, I do. The things I do want to do, I do not do."
So Paul said there were two conflicting laws working within him. There was the law of his mind—which loved God, understood a great deal about God, wanted to submit to God, wanted to sacrifice for God's sake and in His name, wanted to discipline himself. But the law of his flesh, sin that dwelt within him, put up its ugly head and, every once in a while, it would break out.
We do have to discipline ourselves. "Putting on" and "taking off" is not always easy. Sometimes we find that there are certain things that we can do readily. It almost seems like it comes easily to us. But there are other things that are like a thorn in the flesh, and they gnaw away at us, and embarrass us from time to time, and make us feel guilty. They make us wonder whether we will be acceptable before God. They embarrass us, and we wish they were not there. And we know that it takes a great deal of work. Work requires discipline. We know that we are to "put off" those things that do not fit the image of God, and to "put on" the characteristics that do.
The final thing that he mentions there really is love. Love is the crown. It is what tops off, as it were, all of the other virtues and ties them all together. The "putting on" and the "taking off" will actually be the manifestation of the seeking God and those things which are above.
Even when we understand this, even the ability to do this—to "put on" and to "take off"—is a gift from God. The resources to do this come from Him. God responds to those who make Him the focus of their lives. And this is the way that it is exhibited. The evidence begins to show in the way we live our lives.
So those are the kinds of names we used to carry, but we no longer do. We are now Christians with a new name.
