The "second coming" is fallacy and never should be portrayed by the Sons of God.
The passage reads, "So Christ was once offered to bear the sins of many; and unto them that look for Him shall He appear THE SECOND TIME without sin unto salvation" (Heb. 9:28). This verse can be rightly divided only when taken within the context of the verses preceding it. The writer says, "For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us: Nor yet that He should offer Himself often, as the high priest enters into the holy place every year with blood of others; for then must He often have suffered since the foundation of the world: but now once in the end of the world has He appeared to put away sin by the sacrifice of Himself" (Heb. 9:24-26).
Some have tried to find three "appearings" in these verses, but there are only two. And the words are taken by unthinking people as though "appear the second time," or "second appearing" were somehow the equivalent of, or a synonym for, the "second coming." But this is merely playing on the language of our English version. The two "appearings" in this passage not even refer to the so-called "first coming" of the Christ in Bethlehem's manger, or His "second coming" from heaven at the end of this age. As we shall see later, the Lord has had MANY APPEARINGS on this earth. And here TWO of those many appearings are contrasted, the one with the other, so that one is "first," and the other "second." Here we have His "first" appearing: IN THE PRESENCE OF GOD FOR US. "For Christ is not entered into the holy places made with hands ... but into heaven itself, now to APPEAR IN THE PRESENCE OF GOD FOR US."
In the types of the Old Testament the atonement for sin was not accomplished with the killing of the animal, and the sprinkling of the blood on the altar, the people and the tabernacle; not until the High Priest presented himself in the Most Holy Place, in the presence of God with the blood of the sacrifice. This was a type of the sacrifice of Christ for our sins. It was not accomplished nor completed with the shedding of His blood and His death on the cross. Before there could be any efficacy to His sacrifice He had to PRESENT HIMSELF IN THE PRESENCE OF GOD by His own blood to make atonement for our sins. This is what this verse is speaking about; Christ entered the Holiest, not of the earthly tabernacle, but into heaven itself, presenting Himself, appearing before the presence of God, in the eternal realm of spirit, as the bearer of our redemption. This verse says that He APPEARED in the presence of God for us. This is the first of the two appearings here contrasted, but certainly NOT His first appearing unto men! As we follow on in this scripture we are told that the Christ needed not to offer Himself often as did the High Priest of the Old Covenant, once a year with the blood of others. Only once did He need to offer Himself, as we read, "But now ONCE in the end of the age has He APPEARED (in heaven - vs. 24) to put away sin by the sacrifice of Himself." Once He has appeared, the first time, IN THE PRESENCE OF GOD FOR US!
Verse twenty-eight speaks of another APPEARING, even a second appearing in connection with our salvation. It begins with these words, "So Christ was once offered to bear the sins of many (referring to verses 24 and 26 where it says He entered the Most Holy Place in heaven and appeared in the presence of God for us)". Now He appears again the second time: "And unto them that look for Him shall He appear the second time without sin unto salvation." Most Christians believe this verse in referring to what is called the "second coming" of the Lord, a visible appearing at the end of this age. This is not alluding to such a coming at all. The word actually employed is wholly different. It is a general word, and it is the very word used with reference to His manifestation to His disciples after His resurrection. It occurs four times in I Cor. 15:5-8 where it is translated "was seen". The Lord appeared to many following His resurrection. The Lord Jesus appeared to the apostle Paul entirely apart from His two appearings set forth in Hebrews chapter nine. The Lord appeared unto Paul in the form of a bright light above the brightness of the noon-day sun. Jesus manifested Himself to Paul in the form of light to commission him to the work of the gospel. And the Lord said., "Rise, and stand upon your feet: for I have APPEARED unto you for this purpose, to make you a minister and a witness both of these things which you have seen, and of those things in the which I WILL APPEAR unto you" (Acts 26:16).
And further, the definite article must be omitted: "So Christ also, having been once offered to bear the sins of many, SHALL APPEAR A SECOND TIME, apart from sin, to them that wait for Him, unto salvation." That is how the Greek text reads. The statement is not prophetic, but doctrinal; and the doctrine in question is not the so-called "second coming," but the PRIESTHOOD! It is not the prediction of an event to be realized by those who shall be alive on earth at the time of the end, but the declaration of a truth and a fact to be realized by every elect member of the body of Christ, no matter in what dispensation his sojourn upon earth may fall.
Our Lord Jesus Christ appears a second time to those who LOOK FOR HIM, who diligently seek for Him and follow after Him; not any more as a sin offering appearing in heaven for us, but in the mighty manifestation of His power usward, UNTO SALVATION. And this salvation is the work of our great and wonderful High Priest. This same wonderful truth is set forth in Heb. 7:25 in these words, "Wherefore He is able also to SAVE THEM TO THE UTTERMOST that come unto God by Him, seeing He ever lives to make intercession for them." This phrase is given by Phillips as "He can save fully and completely." Young's Literal, "He is able to save to the very end." Amplified, "He is able to save to the uttermost - completely, perfectly, finally, and for all time and eternity."
