1. Can Jesus come this year 2017?
No, for the temple of God has not been built so that the man of sin (Antichrist) to reveal himself, showing himself as God. Whoever believes that Our Lord can come anytime (before the great apostasy and the temple of God) has already been deceived.
2Thess 2:1-4 Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, not to be soon shaken in mind or troubled, either by spirit or by word or by letter, as if from us, as though the day of Christ had come. Let no one deceive you by any means; for that Day will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition, who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God.
2, He is God and can come anytime!
Though God is all sovereign and can do what He wants, He Is still a righteous (cannot sin) and faithful God (cannot lie). Since God cannot sin nor lie, then He cannot come again for His saints (Rapture) without the temple of God or the fulfillments of all His end time prophecies, such as the great apostasy, gospel preached to all people, etc.
3. Are we living in the last days?
We must study the end time prophecies of our Lord Jesus Christ, OT's end time Prophets esp. Daniel, and end time epistles to see whether we are now living in the last days.
Dan 12:4, 9-10 "But you, Daniel, shut up the words, and seal the book until the time of the end; many shall run to and fro, and knowledge shall increase."... Although I heard, I did not understand. Then I said, "My lord, what shall be the end of these [things?" And he said, "Go your way, Daniel, for the words are closed up and sealed till the time of the end."
So if we are living in the last days, then we will be able to understand end time prophecies, for God will revealed them to us then.
