This is right up my alley. I feel the same and do as much.

from a blog that Debbie Anderson reads and posted from.

I've always felt that ministry is simply loving people with the gifts and abilities God has given us. No church building or ministry-coordinator-approval required. Loving children by caring for them, loving husbands and wives by serving and partnering with them, loving friends by listening...all these things are ministry. It is Christ living in us and touching people with our skin, speaking to them with our voice and our words, serving them with our hands and feet.

Your letters, sent from one house to another, are ministry too. It is a gift of time and love to write words, to respond to another's heart and mind. Your letters matter. Next time you get out that pen and paper, take a moment to pray over your words. Include something that you know will bless and encourage. Send that letter off with all the peace and joy you can find. Your hour of writing will become work done unto the Lord and true ministry. The loved one on the other end will know it and be blessed.
