What does Ephesians 1:14 mean?
The final verse of this first major section calls the Holy Spirit "the guarantee" of those parts of the inheritance which we do not yet have. In verse 13, the Holy Spirit was called a "seal;" here He is also called a guarantee. The ideas are virtually identical. Both are symbolic of a promise, or a validation, made by someone in authority. Here, it invokes the idea of a financial backing for an investment. The believer's yet-to-be-received inheritance—eternity in heaven with the Lord—is guaranteed by the Holy Spirit.Again, as in verse 12, verse 14 refers to "the praise of [God's] glory." This repeated theme marks the end of this section, and highlights the goal of the Holy Spirit's work in a believer's life: God's glory. The same glory mentioned regarding Jesus is also associated with the Holy Spirit. This again indicates Paul's view of God as triune, with Father, Son, and Spirit each part of the divine Godhead, each eternal, equal, and perfect (Matthew 28:19–20).
