"To me, who am less than the least of all the saints, this grace was given, that I should preach among the Gentiles the unsearchable riches of Christ..." (Ephesians 3:8; NKJV).
Unsearchable - not tracked out, i.e. (by implication) untraceable (Strong's); that cannot be traced out, that cannot be comprehended (Thayer's).
Riches - wealth (Strong's); universally, fullness, abundance, plenitude (Thayer's).
The riches of Christ cannot be traced. They cannot be tracked out. They cannot be comprehended.
33 O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out!
34 For who hath known the mind of the Lord? or who hath been his counsellor?
35 Or who hath first given to him, and it shall be recompensed unto him again?
36 For of him, and through him, and to him, are all things: to whom be glory for ever. Amen.
Romans 11:33-36; KJV
