I understand where you are coming from....when I first joined a christian forum I would log out daily and be full of anger towards others who didn't believe as I did....I would get into some pretty heated debates contending for the faith....This isn’t arguing...it’s contending for the faith. The Greek word for contend means ”to contend strenuously in defense of.” Strenuous means ”requiring or using great exertion, laborious, vigorous, zealously active.” So contending for the faith is a heavy task not to be taken lightly.
problem with this is that my tone and condescending rhetoric alienated those I was speaking to and I lost all hope of ever being a true disciple of Christ to speak the Truth in Love and let the Holy Spirit manifest that seed in them.
I had to leave the forum for awhile until I could get my attitude right. So now I try to humbly share my faith...let God's Word speak for itself....and politely agree to disagree.
