''So then, what does "love" in that context of "God is Love" mean''
The bible itself tells you that. I don't add anything;
1 John 4:7-8; Dear friends, let us love one another, for love comes from God. Everyone who loves has been born of God and knows God. 8Whoever does not love does not know God, because God is love.
''And like I said, if someone does not know God, how can they possibly know what "love" in that context means.''
Again, the bible describes the attributes of the very kind of love it happens to be referring to. I add no ideas or beliefs of my own:
1 Corinthians 13; Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 6Love does not delight in evil but rejoices with the truth. 7It always protects, always trusts, always hopes, always perseveres.''
