Luke 8:10 And he said, Unto you it is given to know the mysteries of the kingdom of God: but to others in parables; that seeing they might not see, and hearing they might not understand.
1Co 4:1 Let a man so account of us, as of the ministers of Christ, and stewards of the mysteries of God.
1Co 14:2 For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him; howbeit in the spirit he speaketh mysteries.
Would love to do this Bible study for you, but this is one you need to do for yourself. There are mysteries about your life, your individual giftings, callings, purpose that only Holy Spirit can reveal to you, personally. The way He does this, is through you, taking time alone, praying in other tongues. When you do, you will find, as I have, that indeed, Heb 11:6 But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.
Seek Him today, pray in other tongues, get lost in the Holy Spirit. He is always worth the pursuit…
