Picture the comic strip detective holding his magnifying glass, hunched over, following the clues. Picture the hunter in the thick brush with his hound trailing the scent of some wild game. In both of those illustrations, there is something that is trackable, in order to reach the end of locating and securing that which has been tracked, so that the tracking is completed.
In regard to the “riches” that are found in Christ, Paul says that the above type of “tracking” cannot be done. He uses a compound word in Ephesians 3:8 (translated “unsearchable” and “unfathomable”), which literally means “not to be tracked out.” The New Testament tells us about the “riches” that belong to Christians, but we will never be able to reach the end of fully comprehending them here or even “tracking” them all down.
Doesn’t that just fill you with joy and encouragement?! The detective and hunter will track something down and then be done. The Christian will never be done with tracking down his rich blessings in Christ!
