Seek Jesus
Before anything else, now that you have recognized the fact that God has super-naturally snatched away His people, do not delay in seeking Jesus and making Him the Lord of your heart.
If hadyou've been trusting in yourself and somesomething you hadyou've done, it's time to repent and start placing your trust completely in Jesus.
Then he said to Jesus, “Lord remember me when You come into Your kingdom.” Jesus said to him, “Assuredly, I say to you, today you will be with Me in Paradise.”
But Paul called with a loud voice, saying, “Do yourself no harm, for we are all here. Then he called for a light, ran in, and fell down trembling before Paul and Silas. And he brought them out and said, “Sirs, what must I do to be saved?” So they said, “Believe on the Lord Jesus Christ, and you will be saved, you and your household.”
Rom 10:9 that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved.
Rom 10:10 For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation.
Rom 10:11 For the Scripture says, “Whoever believes on Him will not be put to shame.”
Rom 10:12 For there is no distinction between Jew and Greek, for the same Lord over all is rich to all who call upon Him.
Rom 10:13 For “whoever calls on the name of the LORD shall be saved.”
Eph 2:8 For by grace you have been saved through faith, and that not of yourselves; it is the gift of God,
Eph 2:9 not of works, lest anyone should boast.
What really happened to all of those who disappeared?
No, it wasn't aliens!
1Th 4:17 Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord.
If there appear to be non-human beings around claiming to be aliens or anything else, we know what they are: demonic spirits who fell with satan. The Bible warns about satan and his ministers being able to falsely appear to us like angels of light.
2Co 11:13 For such are false apostles, deceitful workers, transforming themselves into apostles of Christ.
2Co 11:14 And no wonder! For Satan himself transforms himself into an angel of light.
2Co 11:15 Therefore it is no great thing if his ministers also transform themselves into ministers of righteousness, whose end will be according to their works.
A time of great deception
Mat 24:24 For false christs and false prophets will rise and show great signs and wonders to deceive, if possible, even the elect.
