I realized I had not been on here for a few days, and I thought I would add something to what Herman Blaydoe wrote.
1 Peter 3:15 is a great verse, and helpful to those who have sanctified God in their heart, and who have gentleness and the fear of God. I am not there yet. In fact, I have a lot of making up to do.
When I was first baptized, I thought it was my duty to "be prepared," but I probably pushed more people away from the Church because of my untamed zeal than I want to know about; speaking in a passionate, not yet purified and unenlightened manner is dangerous for all involved. In reality, someone like myself is too incompetent to talk about religion to those outside of the Church. People like myself will never convert anyone, or help in the process. I wish I had realized this over 20 years ago when I first converted.
It is likely most, if not all Orthodox Christians can fulfill this requirement (except for a few sobs I know who are destined for hellfire). I am not there yet.
When I meet the criteria for this verse: experience in hesychia ("Sanctify the Lord God in your hearts," according to Way of a Pilgrim), and have the gentleness and fear of God with which to speak ("with meekness and fear") then maybe I will think for a short time about whether or not I should ask for a blessing to preach, or at the very least actively engage in dialogue with any heterodox that may be passing by.
That is all for now. I forgot how exhausting internet conversations can be!
