I always telling people about my believe in Christ at every opportunity I have. I never push my believes on anyone and I hate when other people do that.identifying as a Christian can also scare people off. You could be pegged as just another religious fanatic trying to recruit... then they will shut you I down faster than a JW on your front porch.
But according to what is written in the Bible, I think it is a good practice to show others your believes and your life in Christ.
Matthew 10.32-33
32."Everyone, therefore who acknowledges Me before others, I also will acknowledge before My Father in Heaven,
33.but whoever denies Me before others, I also will deny before My Father in Heaven."
(Matthew 10.32-33) (Mark 8.38) (Luke 9.26, 12.8-9)
Mark 8.38
38."Those who are ashamed of Me and of My Words in this adulterous and sinful generation, of them the Son of man will also be ashamed when He comes in the glory of His Father with the holy angels.”
Luke 9.26
26."For, whoever is ashamed of Me and My words, of him will the Son of Man be ashamed when He comes in His glory, and the glory of the Father, and of the holy angels."
Luke 12.8-9
8."And I say to you, everyone who confesses Me before men, the Son of Man shall confess also before the angels of GOD,
9.but he who denies Me before men, shall be denied before the angels of GOD."
Luke 6.49
49."But the one who hears and does not act, is like a man who build a house on the ground without a foundation. When the river burst against it, immediately it fell and great was the ruin of that house.”
You are absolutely right when you said that revealing yourself as Christian can scare people off, and sometimes even much worst, people got angry and frustrated, and I do not blame them. This is due particularly to Jehovah Witnesses, who are very annoying guys and who drive people crazy by putting pressure on them to accept Christ, such practice does more harm than good.
But most disgusting for the people when evangelists and missionaries presented themselves as godly, righteous, and good, and in their fakeness is so obvious to ordinary commoner that indeed after meeting them people simply run away or got so angry that sometimes possess even physical threat.
It never happened to me, because I never ask the most stupid and ridiculous question that evangelists usually asked, "Do you believe in Christ?" Or, "Do you know that Christ died for you?"
Such talk turn people away immediately, because many people already very well familiar with their hypocrisy, insincerity, dishonesty, double standards, duplicity, and pretense. Many people already visited church and never return back.
But I use a different tactic to approach people and usually say that I believer in Christ, or if occasion is right I quote some place from the Bible, and quite often people start asking me questions, or express their opinion or their own experience with religion. And sometimes I found a fellow Christian.
I gained this experience from the Bible when I read how Jesus Christ, and Paul, and Peter, and other disciples of Christ approached people and talk to them, and wisely using their experience I always have very positive response.
