'Secrets' in the Bible

"Because," He replied, "while to you it is granted to know the secrets of the Kingdom of the Heavens, to them it is not.

"To you," He replied, "it is granted to know the secrets of the Kingdom of God; but all others are taught by parables, in order that they may see and yet not see, and may hear and yet not understand.

on the day when God will judge the secrets of men's lives by Jesus Christ, as declared in the Good News as I have taught it.

Therefore form no premature judgements, but wait until the Lord returns. He will both bring to light the secrets of darkness and will openly disclose the motives that have been in people's hearts; and then the praise which each man deserves will come to him from God.
