Greater love is great, but nowhere in the Bible does it say that is a ticket to Heaven.
“Jesus said to him, “I am the way, and the truth, and the life; no one comes to the Father but through Me.” — John 14:6
“Jesus said to him, “I am the way, and the truth, and the life; no one comes to the Father but through Me.” — John 14:6
However, if there is no greater love than to lay down one's life for a friend, then it is at least equal to love of Christ. Combine those two and it appears that Christ may choose those who lay down their life for another.
Who knows what happens in that last split second of life?
