@Leadfoot,
That is only evidence of it, not the definition of it. If there is no suffering their is no love. Jesus set down the definition by example of love. To suffer wrongfully but do it willingly. Love is an action not a feeling.
1 Pet 2:19-22
19 For this is commendable, if because of conscience toward God one endures grief, suffering wrongfully.
20 For what credit is it if, when you are beaten for your faults, you take it patiently? But when you do good and suffer, if you take it patiently, this is commendable before God.
21 For to this you were called, because Christ also suffered for us, leaving us an example, that you should follow His steps:
22 "Who committed no sin, nor was deceit found in His mouth";
