Yet Samson is listed in the Hebrews 11 “Hall of Fame of Faith.”
32 And what more shall I say? For the time would fail me to tell of Gideon and Barak and Samson and Jephthah, also of David and Samuel and the prophets: 33 who through faith subdued kingdoms, worked righteousness, obtained promises, stopped the mouths of lions, 34 quenched the violence of fire, escaped the edge of the sword, out of weakness were made strong, became valiant in battle, turned to flight the armies of the aliens.
Hebrews 11:32-34 NKJV
I think at least part of the reason Samson is a hero of faith is that he finished well.
28 Then Samson called to the Lord, saying, “O Lord God, remember me, I pray! Strengthen me, I pray, just this once, O God, that I may with one blow take vengeance on the Philistines for my two eyes!” 29 And Samson took hold of the two middle pillars which supported the temple, and he braced himself against them, one on his right and the other on his left. 30 Then Samson said, “Let me die with the Philistines!” And he pushed with all his might, and the temple fell on the lords and all the people who were in it. So the dead that he killed at his death were more than he had killed in his life.
Judges 16:28-30 NKJV
In these last of the last days, may we all forget our failures and press on!
12 Not that I have already attained, or am already perfected; but I press on, that I may lay hold of that for which Christ Jesus has also laid hold of me. 13 Brethren, I do not count myself to have apprehended; but one thing I do, forgetting those things which are behind and reaching forward to those things which are ahead, 14 I press toward the goal for the prize of the upward call of God in Christ Jesus.
Philippians 3:12-14 NKJV
Jesus is coming very soon. Be ready!
4 But you, brethren, are not in darkness, so that this Day should overtake you as a thief. 5 You are all sons of light and sons of the day. We are not of the night nor of darkness. 6 Therefore let us not sleep, as others do, but let us watch and be sober.
1 Thessalonians 5:4-6 NKJV
32 “Now learn this parable from the fig tree: When its branch has already become tender and puts forth leaves, you know that summer is near. 33 So you also, when you see all these things, know that it is near—at the doors! 34 Assuredly, I say to you, this generation will by no means pass away till all these things take place. 35 Heaven and earth will pass away, but My words will by no means pass away.”
Matthew 24:32-35 NKJV
34 “But take heed to yourselves, lest your hearts be weighed down with carousing, drunkenness, and cares of this life, and that Day come on you unexpectedly. 35 For it will come as a snare on all those who dwell on the face of the whole earth. 36 Watch therefore, and pray always that you may be counted worthy to escape all these things that will come to pass, and to stand before the Son of Man.”
Luke 21:34-36 NKJV
