Salvation is about life and death. Would you want your doctor to take the same approach with someone who has cancer? Build a relationship with them and be their friend? No! You would want him to give them the truth of their condition.
How are men saved? Not by relationships. Not by friendships. But by the gospel.
Romans 1:16
For I am not ashamed of the gospel of Christ:
for it is the power of God unto salvation to every one that believeth;
Good tracts have the gospel printed on them and open up a conversation to share the gospel with them by using your mouth. At least you're giving them a bible.
