Relationship to God in Christ is the ultimate blessing. Paul warns that understanding all mysteries is no substitute for this, and indeed, John, the beloved disciple, declares that 'God is love'. My own personal walk of grace (some 53 years) affirms this. Knowing and understanding 'all mysteries', for me, is secondary to knowing Jesus personally. John 14:3 and the blessed hope is special to the Church, Christ's beloved bride. Song of Solomon; Psalm 45. Praise God for GRACE-through-FAITH. Amen.
