“so ( first coming ot promises ) Christ was once offered to bear the sins of many;
and ( second coming nt promises ) unto them that look for him shall he appear the second time without sin unto salvation.”
Hebrews 9:28 KJV
“Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince
shall be seven weeks,
and threescore and two weeks: the street shall be built again, and the wall, even in troublous times.”
Daniel 9:25 KJV
If you keep reading
“And after threescore and two weeks shall Messiah be cut off, but not for himself (first coming the messiah was rejected and killed , bearing the sins of the people )
and the people of the prince that shall come shall destroy the city and the sanctuary; ( rome destroyed Jerusalem and it’s temple shortly after )
and the end thereof shall be with a flood, and unto the end of the war desolations are determined.”
Daniel 9:26 KJV
This is why Jesus was warning those of that region and tbat generetion about the coming destruction of Jerusalem and it’s temple
The first coming already happened it’s the gospel . daniel wrote it 700 yes before it happened . His first coming fulfills all of the promises to Israel about the messiah who would die for thier sins ( Isaiah 53, psalm 22) and concerned the end of Jerusalem and its temple and ways of worship because the time given then was for them to cease from sin and accept the messiah, they rejected him and had him killed bringing the desolation of the curses of the law . that was his first coming then he went to heaven
“And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel; which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven.”
Acts 1:10-11 KJV
He’s going to return the second time from heaven for a different purpose not to be manifest as a man and die for sins again but to save his people and judge the world in righteousness by the truth of his everlasting word
his second coming will be at the end of the world when the dead are raised up for judgement
“Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, and shall come forth;
they that have done good, unto the resurrection of life;
and they that have done evil, unto the resurrection of damnation.”
John 5:28-29
“For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works.”
Matthew 16:27 KJV
“For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad.”
2 Corinthians 5:10 KJV
“And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them.
And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works.
And whosoever was not found written in the book of life was cast into the lake of fire.”
Revelation 20:11-12, 15
his return the second coming will be about deliverance for his people and then judgement for the earth nonone knows the time
Deliverance for his people
“For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.”
1 Thessalonians 4:16-17 KJV
judgement for his enemies
“….the Lord Jesus shall be revealed from heaven with his mighty angels, in flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ: who shall be punished with everlasting destruction from the presence of the Lord, and from the glory of his power;
when he shall come to be glorified in his saints, and to be admired in all them that believe in that day.”
2 Thessalonians 1:7-10 KJV
His first coming is what we read about in the gospel his second is at the end of the world judgement day the things written in the nt that they tell us is coming
