Many commentators, including Jewish, have applied these words to secret sins, known only to God, as in Ps. 19:12. The parallel expression, however, “those things which are revealed,” that is, “unto us,” implies that the “secret things” are things God has not seen fit to reveal. Man cannot fathom the inner counsels of the Almighty. They are His. The things He has revealed, of law and life, are ours to contemplate. In the Scriptures we have the revealed will of God; it is all ours.
