Ephesians 4:4-6 illustrates the unity of God’s people with the very familiar words, “There is one body and one Spirit, just as you were called in one hope of your calling; one Lord, one faith, one baptism; one God and Father of all, who is above all, and through all, and in you all.” Paul had just encouraged them to be unified in vv. 1-3. Unity is necessary because in v. 16 it is written, “From whom the whole body, joined and knit together by what every joint supplies, according to the effective working by which every part does its share, causes growth of the body for the edifying of itself in love.”
The church has one purpose and mission, but it is composed of many different people. I’ve known of a lot of Christians who believe they aren’t useful so they quit. Our single goal is to glorify God, and all parts are necessary for the glorification of God. Paul wrote eloquently about the body of Christ in 1 Corinthians 12:12-25. The analogy of the body and the members enlighten us that we should care for one another, and that each member is important.
You are important, so don’t give up serving God — even though you may feel insignificant. In the parable of the talents, God commended the two servants who were given talents and then increased them (Matthew 25:14-30). They were referred to as “good and faithful servants,” even though the nature and usefulness of their talents weren’t revealed. The point to remember is that the Lord and His people need whatever talents you possess.
