We have already been over the Samson and Solomon issue before. Here is my reply to you that I said before,
"No, you are again twisting around what I have said out of context. I said Solomon and Samson are examples in the Bible of how NOT to live. They are not examples for us to point to so as to think we can live that way, too. I never said that, nor implied such a thing. You are forcing that false belief upon me (of which I reject). Samson and Solomon were not looking at other believers who lived like they did thinking they can get away with sin. God knew their heart and knew that while they did live sinful lives, they turned at the last moment at the end and made things right with the Lord. This is not a support of the Antinomian or Classic OSAS type belief. It runs contrary to it because the Antinomian believer will just continue to live like an evil sinful version of Solomon or a Samson until they die. For they will not admit in what they have done is wrong. For they believe all future sin is paid for and that nothing can remove them from Christ because they are sealed by the Spirit. Sin is only physical death and not spiritual death to the Antinomian believer. Hence, why holiness is rarely ever stressed as being a requirement in being a true believer.
Anyways, on your other point on how Samson and Solomon were not saved: Well, ...
As for Samson:
Samson was saved for two reasons. One, God granted His request and gave Samson the strength to take down the two pillars. Why would God answer the prayer of an evil unsaved man and make it look like He was in favor with Him by giving Him the strength by the Spirit? Two, why is Samson mentioned in Hebrews 11 among the heroes of faith if He was unsaved? If you want to discuss this point more, go here:

As for Solomon:
2 Samuel 7:12-16 tells us God would take away his mercy from Saul but he would not take away it away from Solomon. For God says that He will be a father to Solomon and he will be like his son, if he commits iniquity he will be chastened by the Lord with a rod of iron. We know this passaged is clearly speaking about Solomon because verse 13 describes him as one who will build a house in his name (i.e. the Temple). It is also evident that Solomon was the author of Ecclesiastes, too.
