As you know leading someone to God is not a job for cowards. It takes phenomenal courage to step out boldly and put yourself in a vulnerable position. It isn't what you say that counts it's what you do. The clique is true "I don't care how much you know until I know how much you care."
Here are some tips on reaching those who cross your path:
1. Memorize some Bible verses that you can use to shore up your courage.
2. Say your prayers before each encounter.
3. Be aware that anyone you encounter may only have two frames of mind: Fight or Flight.
4. Above all, make no assumptions. THEY DON'T NEED YOU AS MUCH AS YOU NEED THEM. (this is the attitude you must have if you want to make a difference.)
Always be willing to share your faith, pray with someone, or give them a Bible. The keys to a good relationship are: respect, consistency, encouragement, and support.
