It is true that the Scriptures often warn us against deception, and it is true that some preach “another Jesus” (who is not Jesus at all) and “another gospel” (which is no gospel at all; see 2 Cor. 11:1-4;
I wish that you would be patient with me in a little foolishness, but indeed you are being patient with me! 2 For I am jealous for you with godly jealousy, because I promised you in marriage to one husband, to present you as a pure virgin to Christ. 3 But I am afraid that just as the serpent deceived Eve by his treachery, your minds may be led astray from a sincere and pure devotion to Christ. 4 For if someone comes and proclaims another Jesus different from the one we proclaimed, or if you receive a different spirit than the one you received, or a different gospel than the one you accepted, you put up with it well enough!
Gal. 1:6-9
6 I’m amazed that you are so quickly deserting the one who called you by the grace of Christ to follow another gospel. 7 It’s not really another gospel, but certain people are confusing you and they want to change the gospel of Christ. 8 However, even if we ourselves or a heavenly angel should ever preach anything different from what we preached to you, they should be under a curse. 9 I’m repeating what we’ve said before: if anyone preaches something different from what you received, they should be under a curse!
And it is true that many false converts will be shocked when Jesus says to them on that great and dreadful Day, “Depart from me” (see Matt. 7:21-23;
21 “Not everybody who says to me, ‘Lord, Lord,’ will get into the kingdom of heaven. Only those who do the will of my Father who is in heaven will enter. 22 On the Judgment Day, many people will say to me, ‘Lord, Lord, didn’t we prophesy in your name and expel demons in your name and do lots of miracles in your name?’ 23 Then I’ll tell them, ‘I’ve never known you. Get away from me, you people who do wrong.’
24 “Everybody who hears these words of mine and puts them into practice is like a wise builder who built a house on bedrock. 25 The rain fell, the floods came, and the wind blew and beat against that house. It didn’t fall because it was firmly set on bedrock. 26 But everybody who hears these words of mine and doesn’t put them into practice will be like a fool who built a house on sand. 27 The rain fell, the floods came, and the wind blew and beat against that house. It fell and was completely destroyed.”
Matt 25:31-46
“Now when the Human One[b] comes in his majesty and all his angels are with him, he will sit on his majestic throne. 32 All the nations will be gathered in front of him. He will separate them from each other, just as a shepherd separates the sheep from the goats. 33 He will put the sheep on his right side. But the goats he will put on his left.
34 “Then the king will say to those on his right, ‘Come, you who will receive good things from my Father. Inherit the kingdom that was prepared for you before the world began. 35 I was hungry and you gave me food to eat. I was thirsty and you gave me a drink. I was a stranger and you welcomed me. 36 I was naked and you gave me clothes to wear. I was sick and you took care of me. I was in prison and you visited me.’
37 “Then those who are righteous will reply to him, ‘Lord, when did we see you hungry and feed you, or thirsty and give you a drink? 38 When did we see you as a stranger and welcome you, or naked and give you clothes to wear? 39 When did we see you sick or in prison and visit you?’
40 “Then the king will reply to them, ‘I assure you that when you have done it for one of the least of these brothers and sisters of mine, you have done it for me.’
41 “Then he will say to those on his left, ‘Get away from me, you who will receive terrible things. Go into the unending fire that has been prepared for the devil and his angels. 42 I was hungry and you didn’t give me food to eat. I was thirsty and you didn’t give me anything to drink. 43 I was a stranger and you didn’t welcome me. I was naked and you didn’t give me clothes to wear. I was sick and in prison, and you didn’t visit me.’
44 “Then they will reply, ‘Lord, when did we see you hungry or thirsty or a stranger or naked or sick or in prison and didn’t do anything to help you?’ 45 Then he will answer, ‘I assure you that when you haven’t done it for one of the least of these, you haven’t done it for me.’ 46 And they will go away into eternal punishment. But the righteous ones will go into eternal life.”
All of us should examine ourselves to be sure that we are “in the faith” (2 Cor. 13:5)
Examine yourselves to see if you are in the faith. Test yourselves. Don’t you understand that Jesus Christ is in you? Unless, of course, you fail the test.
and all of us should be diligent to “confirm [our] calling and election”
(2 Pet. 1:10)
Therefore, brothers and sisters, be eager to confirm your call and election. Do this and you will never ever be lost.
and this does mean falling into performance-based religious exercises but rather living out our calling to be God’s children (see 2 Pet. 1:3-11; this is our response to what God has graciously done for us).
By his divine power the Lord has given us everything we need for life and godliness through the knowledge of the one who called us by his own honor and glory. 4 Through his honor and glory he has given us his precious and wonderful promises, that you may share the divine nature and escape from the world’s immorality that sinful craving produces.
5 This is why you must make every effort to add moral excellence to your faith; and to moral excellence, knowledge; 6 and to knowledge, self-control; and to self-control, endurance; and to endurance, godliness; 7 and to godliness, affection for others; and to affection for others, love. 8 If all these are yours and they are growing in you, they’ll keep you from becoming inactive and unfruitful in the knowledge of our Lord Jesus Christ. 9 Whoever lacks these things is shortsighted and blind, forgetting that they were cleansed from their past sins.
10 Therefore, brothers and sisters, be eager to confirm your call and election. Do this and you will never ever be lost. 11 In this way you will receive a rich welcome into the everlasting kingdom of our Lord and savior Jesus Christ.
At the same time, we need to be very careful about setting ourselves up as the ultimate judge of who is saved and who is lost--meaning, among those who claim to be followers of the Jesus of the Scriptures
