"For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life."

Talking about God's love for man kind is the best thing that has ever happen to man, every aspect of the bible still go down to the bible.

No, in all these things we are more than conquerors through him who loved us. For I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers, nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord

The definition of LOVE is God and God is LOVE

WHAT THE BIBLE SAYS ABOUT GOD'S LOVE
It say that any one who doesn't love do not know God even when we are sinners and done all kinds of atrocities, he is still there for us.

But God shows his love for us in that while we were still sinners, Christ died for us.

LET LOVE LEAD
