According to everything the Bible says to be.<quoted text>
What's a Christian's role in your opinion?
You can't nick-pick what you want to suit you and then disregard the rest conveniently.
If you can't express God's love with mercy and forgiveness towards others then the effort to express the fear of God's wrath & judgment and his hatred towards sin is meaningless thus the message will always fall on deaf ears.
Hate is easy to wield,even for Christian but to be a Christian is to be like Christ.
For if Christ can forgive those who persecuted & ridiculed him as he was hanging on the cross then so must Christians forgive those who persecute & ridicule them because of him.
The true message has and always will be that we have a Heaven to gain and a Hell to shun and that Jesus Christ is the way and the truth.
No one goes to the Father except thru him,Jesus Christ.
Also,Jesus did not come to condemn and damn sinners to Hell but by believing in him and walking in righteousness you will not perish but will have eternal life.
