well the 2nd commandment of JEsus which He said "equally" to the first one(Love God above all)
was to love our neighbors as ourselves. if you believe in this, you would always want others to know
the freedom and Salvation you now have in Christ.
if we are to follow the 2nd commandment, is keeping Christ's good news of our salvation to ourselves promote loving others?
however the best way to preach the gospel is not through words but through our lives.

with Love,Respect and Acceptance over Judgement.
