Where you put, "-- <second coming>", in would put, "The Current Age of Jesus' churches".
I believe:
Jesus died 14 day of the first month and after three days was raised out of the dead, remained on earth forty days and then ascended to the right hand of the Father, Ten days later, fifty days on the morrow after the Sabbath, after the Passover death, God began pouring our his Spirit on the called out ones, the church, Zion. That was on the day of first-fruit,
a holy convocation day, First-fruit of the Spirit indwelling one. The Spirit of adoption, the redemption of the body. The Spirit of that will change one from mortal to immortal, from corruptible to incorruptible.
One should ask oneself, why, first-fruit of the Spirit? Why is fruit preceded by, first? Does it imply likeness of same at a later time?
Acts 15:1-14 speaks of God calling from Judah and the nations (Gentiles if you will) a people for his name ( or for his name's sake).
The next day of,
a holy convocation, is
the day of trumpets.
1 Cor 15:50-52 And this I say, brethren, that flesh and blood the reign of God is not able to inherit, nor doth the corruption inherit the incorruption; lo, I tell you a secret; we indeed shall not all sleep, and we all shall be changed; in a moment, in the twinkling of an eye, in the last trumpet, for it shall sound, and the dead shall be raised incorruptible, and we -- we shall be changed:
What takes place on a holy convocation day of trumpets?
Joel 2:1 Blow ye the trumpet in Zion, and sound an alarm in my holy mountain: let all the inhabitants of the land tremble: for the day of the LORD cometh, for
it is nigh at hand;
Joel 2:15 Blow the trumpet in Zion, sanctify a fast, call a solemn assembly
I believe that to be the coming of the Lord, see also Acts 15:16,17 God is presently taking out of the nations a people for his name awaiting the day of trumpets.
Acts 15:16,17 After this (taking out of the nations a people for his name)
I will return, and will build again the tabernacle of David, which is fallen down; and I will build again the ruins thereof, and I will set it up:
That the residue of men might seek after the Lord,
and all the Gentiles, upon whom my name is called, saith the Lord, who doeth all these things.
Joel 2:28 And it shall come to pass
afterward,
that I will pour out my spirit upon
all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions:
Joel 2:32 And it shall come to pass,
that whosoever shall call on the name of the LORD shall be delivered: for in mount Zion and in Jerusalem shall be deliverance, as the LORD hath said,
and in the remnant whom the LORD shall call.
Acts 15:18 Known unto God are all his works from the beginning of the world.
Known from ages is to the God the works of Him.
I believe the plan was laid out before the foundation of the world and even maybe before, In beginning God created the heavens and the earth.
