1 Corinthians 3:21–23 (KJV 1900)
21 Therefore let no man glory in men. For all things are yours; 22 Whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things to come; all are yours; 23 And ye are Christ’s; and Christ is God’s.
Let no man glory in men (e.g. Apollos, Cephas, Paul); remember they are only men who plant and water (3:5-7). For all things are yours: this is rather unclear until the context is studied. In context, we see the church is built on the foundation of Jesus Christ (3:11), and we are the temple of God (3:16). Because of that, we are in Christ and Christ in us and we possess all things together as one body of Christ.
Which things are ours? All are yours no matter who, what, when, or where we may find ourselves, when we are one in Christ, as his body, ye are Christ’s; and Christ is God’s.
