If you want to honestly proclaim yourself a God believing and honoring man or woman, boy or girl, and if in particular you wish to manifest your proclamation of Jesus Christ as your Lord & Savior, consider the following, on this Good Friday and Easter celebration.
Just because someone declares you to be his or her enemy, you do not have to nor should you declare the other person your enemy in return. Jesus did not.
Plenty of people have declared me (behind my back) their "enemy" because they believe in a totally messed up world view of reincarnation, evil aliens sneaking around, and "payback" and vengeance for real or imagined wrongs. I've never considered even a single one of those people my enemy in turn.
Sin is the enemy, not the people themselves. No matter what a person does to you or if he or she goes so far as declaring you an "enemy," there is no reason for you to accept the invitation to mutual enmity.
The longer someone is your enemy in a one sided enemy relationship, the further he, she or they as a group walk further and further away from God and their own salvation. If you remain just and righteous, believing only in God and fore swearing enmity and malice, you will in turn move closer to closer to God.
Do not proclaim yourself a believer in God and a follower of Jesus Christ and then, in turn, accept invitations (or worse, be tempted to issue) declarations of enmity or even withholding of blessings and prayers for the other side's betterment.
