Will God love those whom He'll punish eternally?

According to the hymn *The Love of God *, God's love "reaches to the lowest hell": >**The love of God** is greater far > >Than tongue or pen can ever tell; > >It goes beyond the highest star, > >And **reaches to the lowest hell** Does the Bible teach anywhere that God loves those in hell? We know that at present, God loves sinners and wants them to repent, but what if they never repent? Does the Bible ever address whether God will still love sinners even after they are cast into hell?
