Introduction
One verse before the great doxology about God doing 'exceeding abundantly above' (v. 20), Paul prays we would know a love we cannot fully know — and be filled with a fullness we cannot fully measure.
Historical Context
Paul prays this on his knees (v. 14) for Gentile believers — proof that the love which once felt exclusive was always wide enough for them.
Original Language Insights
'Passeth knowledge' (hyperballousan tes gnoseos) — overshoots what knowing can hold. The love of Christ is known truly, never exhaustively.
'Filled with all the fulness of God' — the highest petition in the New Testament: every believer is the temple God means to fill.
Theological Significance
Christian knowing is not less than facts but more — it is relational reception of a love whose dimensions only eternity will trace. The prayer is impossibly large because the God it addresses is impossibly generous.
Practical Application
Don't shrink your prayers to fit your imagination. Pray Paul's prayer back to God — He delights to answer it.
