This picture represents what the prophets (including Jesus Christ) could see and know from the Scriptures. As you can see here the Prophets could not know or understand anything about the Church Age because God kept it a Secret from everyone until it was revealed to Paul and the other Apostles by the ascended Christ.
And to Him who is able to establish you, according to my good news, and the preaching of Jesus Christ, according to the revelation of the secret, in the times of the ages having been kept silent,
26 and now having been made manifest, also, through prophetic (Christian) writings, according to a command of the age-during God, having been made known to all the nations for obedience of faith —
27 to the only wise God, through Jesus Christ, to him [be] glory to the ages. Amen.
3 that by revelation He made known to me the secret, according as I wrote before in few [words] —
4 in regard to which ye are able, reading [it], to understand my knowledge in the secret of the Christ,
5 which in other generations was not made known to the sons of men, as it was now revealed to His holy apostles and prophets in the spirit —
1 Cor 2:7-8
7 But we speak the wisdom of God in a musterion, secret, even the hidden wisdom, which God ordained before the world unto our glory:
8 Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory.
This one represents the Church of the Body of Christ versus the Kingdom of God and Christ. The resulting affect of this hidden wisdom is that the coming Kingdom which Jesus and the apostles expected soon after his ascension, would be put on hold or held in abeyance. As you can see, the Kingdom most Christians speak about as if it existed today, will not exist until after the Great Tribulation. As for now, Jesus is our Lord, not our king.
2 Peter 3:14-18
Therefore, beloved, since you look for these things, be diligent to be found by Him in peace, spotless and blameless, 15 and regard the patience of our Lord as salvation; just as also our beloved brother Paul, according to the wisdom given him, wrote to you, 16 as also in all his letters, speaking in them of these things, in which are some things hard to understand, which the untaught and unstable distort, as they do also the rest of the Scriptures, to their own destruction. 17 You therefore, beloved, knowing this beforehand, be on your guard so that you are not carried away by the error of unprincipled men and fall from your own steadfastness, 18 but grow in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be the glory, both now and to the day of eternity. Amen.
This revelation is NOT to be ignored; you do so at your own destruction.
Will you be found blameless?
Are you among the untaught (unteachable) and unstable?
Are you being lead astray by the error of unprincipled men?
Are you growing in knowledge as well as grace?
