The real meaning of being full-time is to live to Him. To go full-time does not mean to drop your job and become a preacher. It does not mean that you give up your business and become one who preaches the gospel or who labors in the word all the time. A full-timer is one who lives to the Lord. Who should be such a one? Every believer, without one exception. As long as you are a believer, you have to realize you should be one living to Him. We have to live to Him because He is ours and we are His. To live to Him is based upon the fact that we are His. Not only is He ours, but we also are His….To live to the Lord includes living for, by, with, and in Him. This is one being two and two in one. There is not only no separation between us and the Lord but also no distinction when we are living to Him.
To be full-time means that you live to the Lord. You do not live for Him but to Him. This is a great privilege. A full-timer does not mean what we may think. A full-timer is one who lives to the Lord; every believer, as one bought by the Lord with a price, should be a person living to the Lord. He is yours and you are His. He and you are one. He is to you and you are to Him. There is no distinction in anything. He does not need your permission to use you, nor do you need His permission to use Him.
