This isn't a popular subject, and I'd rather avoid it, but it's important that we Christians be prepared to answer this question:
Why would a loving God send men to hell?
Genuine love has boundaries-- a loving wife expects her husband's faithfulness.
Genuine love is offended by evil and does something about it--a loving father protects his child from molestation.
He gives each man a choice. Review the story of Cain and note God's loving warning (Genesis 4:6-7).
Those who reject Christ choose Hell despite:
- God's testimony in creation (Romans 1:20).
- His Truth written on their hearts (Romans 2:12-16).
- His grace-filled love (John 15:13; John 3:16).*
- His promise that all who seek Him will find Him (Jeremiah 29:13; Luke 11:9-13).
Even if we don't fully understand the concept of hell, we can trust God's just and loving character. (Jeremiah 9:23-24).

If you have heard people deny the concept of hell, please see what the Bible says HERE. It's so important that we know what God's Word says, not the ever-shifting opinions of men.
These are only a few Scriptures that speak of Hell: Matthew 10:28; 2 Thessalonians 1:5-9 ; 2 Peter 2:4-9 ; Revelation 14:11 . If you are confused or doubtful about the concept of Hell, I encourage you to use an exhaustive concordance and find all mentions of Hell, Hades, and Sheol.
