Can a person be a Christian without love, forgiveness and compassion?
I strongly doubt it. Jesus died so that all our sins can be forgiven, Jesus loved us so much that He laid down His life for us. Because He is merciful and compassionate, we are still here.
So I ask again, can a person be a Christian without love, forgiveness and compassion?
Paul said it best in 1 Corinthians 13:
"If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but do not have love, I am nothing. If I give all I possess to the poor and give over my body to hardship that I may boast, but do not have love, I gain nothing."
