The answer of living a holy life (so those around us may be saved) is a difficult one. I totally agree with the idea. Nonetheless, even if I do live a holy life--if I read the Bible, fast, pray, am meek, etc.--that doesn't mean that others will notice, especially early on. People might notice a meek and humble person as living a Christian life, but they're just as likely to overlook the person completely. Unless we can get to the point where it starts transforming us so obviously that others take notice, more overt evangelism is sometimes needed to go along with it. And even if it isn't needed, more overt evangeism is often desireable. Though when I say "overt evangelism" I don't necessarily mean that in the most literal sense. It can be overt without people even realising that you are doing evangelism... because the two intersect, and evangelism and living a holy life are often one and the same. Fwiw, here is a list of fairly non-confrontational ideas for evangelism and talking about the faith:
- Offer to use financial donations for outreach and to help inquirers and visitors. For one example, buy in bulk copies of a book, like The Orthodox Church by Met. Kallistos, which can be given to anyone who visits the parish (whether they call themselves an inquirer or not). Or do something similar at a parish festival--buy materials and give them free to anyone who wants them.
- Get involved in local charity work, from simple stuff like food pantry to more complex stuff like setting up a free clinic once a month using the help of parishioners with medical knowledge. The evangelism here is not preaching the Gospel, but living it.
- Have a full cycle of services, verbally commit to attend such services to your priest, and let people know. Invite people. Some people don't want to "waste" a Saturday going to Church, or get up early on Sunday. Fine... meet them where they are. Let them see that they are wrong, that Orthodoxy is more than worth their time and effort. But going further... maybe they can't get to weekday morning liturgies because they work, so have events in the evening. Have youth groups on a weekday night and some activity for the parents scheduled at the same time.
- Use your skills, and ask others to. Good at fixing cars? Offer yourself for giving advice or help. Replacing someone's brakes can be evangelism. So can changing someone's oil. Or fixing their leaky faucet. Or something as simple as giving them a ride to church if they don't have a car (or have some other need).
- Organize special events where the public are invited beyond the typical festivals. My protestant church, for example, always did a free breakfast for the public very early on the first day of buck season. Did anyone ever start attending our church because of it? I don't know. But "try and see" is not just a slogan to say to others, it's something we need to take to heart ourselves.
- Make an effort to chat to people, in school or work or wherever, about topics that aren't overtly religious but can lead into a discussion of the faith if the purpose shows interest. To give an example, I'm currently doing a paper on Dostoevsky, and it is related to his views about doubt. Throughout the semester I will be meeting with various classmates while I develop it, and will be talking to them. Not that this was my intention originally--but simply as a happy by-product--I will be able to mention Orthodoxy and religion while I talk about Dostoevsky, and I'll be able to do it in a manner that is not at all confrontational or pressuring. Similar scenarios can be thought of for work, family gatherings, etc., if we want to be "as wise as serpents and as harmless as doves"
