What happens to boastful prideful people in the Bible?

Answer 1

Not all boasting and being proud is a bad thing when it is used with the right intent. Nearly all of the Apostle Paul's letters mention his boasting and a few his pride serving Christ. Here are two examples:

2 Corinthians 10:13New International Version (NIV)

13 We, however, will not boast beyond proper limits, but will confine our boasting to the sphere of service God himself has assigned to us, a sphere that also includes you.

Romans 11:13

New International Version (NIV)

13 I am talking to you Gentiles. Inasmuch as I am the apostle to the Gentiles, I take pride in my ministry

However, like with most things, if our intentions are for our selfish gains and not the love of others or to honor God, then these we are warned to avoid as they are setting their own fate - particularly those as we approach the end-times:

2 Timothy 3:2-8New International Version (NIV)

2 People will be lovers of themselves, lovers of money, boastful, proud, abusive, disobedient to their parents, ungrateful, unholy, 3 without love, unforgiving, slanderous, without self-control, brutal, not lovers of the good, 4 treacherous, rash, conceited, lovers of pleasure rather than lovers of God- 5 having a form of godliness but denying its power. Have nothing to do with such people.

6 They are the kind who worm their way into homes and gain control over gullible women, who are loaded down with sins and are swayed by all kinds of evil desires, 7 always learning but never able to come to a knowledge of the truth. 8 Just as Jannes and Jambres opposed Moses, so also these teachers oppose the truth. They are men of depraved minds, who, as far as the faith is concerned, are rejected.

The Apostle John speaks of pride this way:

1 John 2:16

New International Version (NIV)

16 For everything in the world-the lust of the flesh, the lust of the eyes, and the pride of life-comes not from the Father but from the world.
