The Greek hapas means all, the whole, everyone, the entirety. A strengthened form of pas (G3956), it emphasizes totality and comprehensiveness — often stressing that no exceptions exist. It is frequently used to describe the entire group of disciples, believers, or humanity.
Hapas appears at key moments of divine inclusivity and sovereign action. At Pentecost, hapantes (all) were filled with the Holy Spirit (Acts 2:1-4) — the comprehensiveness of the Spirit's outpouring fulfilling Joel 2:28: 'on all people I will pour out my Spirit.' The resurrection appearances are described with hapas: Jesus appeared to 'all the apostles' (1 Corinthians 15:7). Hebrews 2:9 declares that Christ tasted death for everyone (hyper pantos). The 'all things' (hapanta) language in Paul's cosmology — 'all things were created through him and for him' (Colossians 1:16) — emphasizes Christ's universal lordship. The scope of the gospel matches the scope of the word: no one is excluded from the offer of salvation.
