The short answer is YES, they equally literal and effectual. The word 'Advent' has a Latin origin meaning 'the coming,' or more accurately, 'coming toward.
The First Advent of Christ Jesus “first coming” is the birth of Jesus, however, the first advent is also referred to as the rapture (1 Thess. 4:13-18; 1 Cor. 15:50-55; Matthew 24:40-42; Luke 17:34-36).
The timing of the rapture in relation to the tribulation is one of the most controversial issues in Christiandom today. The three primary views are pre-tribulational (the rapture occurs before the tribulation), mid-tribulational (the rapture occurs at or near the mid-point of the tribulation), and post-tribulational (the rapture occurs at the end of the tribulation). A fourth view, commonly known as pre-wrath, is a slight modification of the mid-tribulational position.
First, it is important to recognize the purpose of the tribulation. According to Daniel 9:27, there is a seventieth “seven” (seven years) that is still yet to come. Daniel’s entire prophecy of the seventy sevens (Daniel 9:20-27) is speaking of the nation of Israel. It is a time period in which God focuses His attention especially on Israel. The seventieth seven, the tribulation, is also a time when God deals specifically with Israel. While this does not necessarily indicate that the church could not also be present, it does bring into question why the church would need to be on the earth during that time.
The primary Scripture passage on the rapture is 1 Thessalonians 4:13-18. It states that all living believers, along with all believers who have died, will meet the Lord Jesus in the air. The rapture is God’s removing of His people from the earth. A few verses later, “For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ.” 1 Thessalonians 5:9
The book of Revelation, which deals primarily with the time period of the tribulation, is a prophetic message of how God will pour out His wrath upon the earth during the tribulation. It is inconsistent for God to promise believers that they will not suffer wrath and then leave them on the earth to suffer through the wrath of the tribulation. The fact that God promises to deliver Christians from wrath shortly after promising to remove His people from the earth links those two events together.
Another crucial passage on the timing of the rapture is found in Revelation 3 “Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth.” Revelation 3:10
This means Christ will deliver believers out of the hour of temptation which is the tribulation itself. This is a valid meaning of the Greek word translated “from.” However, it is important to recognize what believers are promised to be kept from. It is not just the trial, but the “hour” of trial. Christ is promising to keep believers from the very time period that contains the trials, namely the tribulation. The purpose of the tribulation, the purpose of the rapture, the meaning of 1 Thessalonians 5:9, and the interpretation of Revelation 3:10 all give clear support to the pre-tribulational position. If the Bible is interpreted literally and consistently, the pre-tribulational position is the most biblically-based interpretation.
The Second Advent or coming of Jesus the Christ is the hope of believers that God is in control of all things, and is faithful to the promises and prophecies in His Word. In His first coming, Jesus the Christ came to earth as a baby in a manger in Bethlehem, just as prophesied. Jesus fulfilled many of the prophecies of the Messiah during His birth, life, ministry, death, and resurrection. However, there are some prophecies regarding the Messiah that Jesus has not yet fulfilled. The second coming of Christ will be the return of Christ to fulfill these remaining prophecies. In His first coming, Jesus was the suffering Servant. In His second coming, Jesus will be the conquering King. In His first coming, Jesus arrived in the most humble of circumstances. In His second coming, Jesus will arrive with the armies of heaven at His side.
The Old Testament prophets did not make clearly this distinction between the two comings. This can be seen in Isaiah 7:14, 9:6-7 and Zechariah 14:4. As a result of the prophecies seeming to speak of two individuals, many Jewish scholars believed there would be both a suffering Messiah and a conquering Messiah. What they failed to understand is that there is only one Messiah and He would fulfill both roles. Jesus fulfilled the role of the suffering servant (Isaiah chapter 53) in His first coming. Jesus will fulfill the role of Israel’s deliverer and King in His second coming. Zechariah 12:10 and Revelation 1:7, describing the second coming, look back to Jesus being pierced. Israel, and the whole world, will mourn for not having accepted the Messiah the first time He came.
After Jesus ascended into heaven, the angels declared to the apostles, “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 1:11.
Zechariah 14, identifies the location of the second coming as the Mount of Olives.
“And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.” Zechariah 14:4
“And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.” Matthew 24:30
Titus 2:13 describes the second coming as a “glorious appearing.”
The second coming is spoken of in greatest detail in Revelation 19..
“And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war. His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself. And he was clothed with a vesture dipped in blood: and his name is called The Word of God. And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean. And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God. And he hath on his vesture and on his thigh a name written, King Of Kings, And Lord Of Lords.” Revelation 19:11-16
