in response to char6... OK, it seems that you have a plan. Since I value your friendship and am concerned about your safety I want to offer you a few pointers.
Do not for any reason attempt to go out and try to minister to the homeless alone, especially at night. This is a risk and even more so since you are a woman. Night time ministry is best done by men and should be done in groups of 3. If you feel the need to reach out to a young lady, do it during the day. There are some ladies that will not respond to men because they have been hurt by them, but you do need to have someone with you in reaching out to women also.
Another good idea is to dress for the part. I don't mean dress down, but it's best not to wear expensive clothes and don't carry a purse.
Do not offer money, rides in your car, or tell anyone where you live. Offer them the what they need, food, clothing, and blankets. You could hand out a tract to them, and invite them to your church, but don't push God onto them. Showing love is the first step, plant the seed and allow God to lead and do the rest.
I don't know the area where you are located, but here on any given night you can drive through the streets and see those who are hurting. Some towns do not have shelters and these hurting people are left to seek a place to sleep and be on guard for their safety when night time comes.
Remember that some of these people are desperate, and you have to keep that in mind when you open your heart to them. Do not tell them how to live, or counsel them on what they did wrong. Ministry is not to freedom to correct because we have not walked in their shoes or share their pain. Ministry is sharing love and empathy wherever it's needed.
I suggest you start at a homeless shelter, or a soup kitchen. This will keep you safe, and allow God to show you who to reach out to. You will get to know the regulars that go there and that makes reaching out to then a lot easier.
I have done street ministry, but I would not allow my wife to do it, and I am only offering these suggestions to you in regards to your safety.
So begin with prayer, allow God to lead, and stay safe. One of the greatest blessings we can receive is when we give of ourselves without expecting anything in return, because that's when God blesses us the most. You may reach out to many but only affect a few, but reaching out in love is the example Christ left for us.
I will keep you in my prayers, and look forward to seeing the direction your ministry takes.
Take care & God Bless
