One cannot be a Christian and have no fruit. Indeed, all Christians yield some measure of all the fruit of the Spirit. It is not that one receives the fruit of love and another the fruit of joy. All the fruit is to be manifest in all Christians.
The degree of the manifestation of the fruit of the Spirit may vary from Christian to Christian, and even episodically in the individual Christian’s life. The Holy Spirit produces the fruit. The fruit of the Spirit is part of the Spirit’s work of sanctification. Sanctification is not a monergistic work; it is synergistic: It involves and requires the cooperation of the believer. We are working out our salvation while at the same time God is working within us.
All of our labor in sanctification would yield no fruit if God were not working in us. Ultimately, it is His fruit in that He is the source of it and power for it. But the full measure of the fruit of the Spirit requires that we work. We are to work not casually or occasionally. Our labor is to be done in fear and trembling.
God is at work within you. Are you cooperating?
