Frustration yet Perserverance...

Forgive me if I spelt (you didn't know it, but I'm English :) )that wrong...today has been a frustrating day. Long story short I'm getting very tired of doing something for someone and never getting anything in return. I've been battling with this all day long, I am exhausted with continually trying to befriend someone, yet they dont seem to want to be friends with me...so you say move on, right? Well let me give you a little history, it is a relationship that has a crazy beginning honestly the most random meeting ever, we were introduced by a man who knew me at age 5. We met 5 years ago, and since I met this person I have grown SO much in the Lord as I learned to listen to the Holy Spirit and follow His prodding (sp?) This friend is a decent friend when I approach them, hardly ever am I approached by them. Well this friend is now in a discipleship program for 6 months (starting in January) and I have been sending notes of encouragement off and on since the beginning. This program allows the students to write mail in return and I have not recieved anything back, which is frustrating (I just wanted to know what they are learning..). So I've been thinking...do I continue to send letters? (b/c satan is wispering in my ear, andrea don't do it, stop writing they don't care, so on so forth). However, this afternoon after battling this yesterday evening through this morning the Lord and I had some good one on one time. Basically this is what I was reminded of: Just like this friendship has taught me from day 1, it is what it is because of the Lord and His instructions of what I am to do. I have been blessed in so many ways by seeing how the Lord has worked when I simply did what I was called to do. I made a committment to this friend in December telling them not only would I be praying for them, I would write them letters while they were away. I do what I do because its what the Lord has told me to do period...why in the world would I second guess anything else that goes along with that...as well as I was reminded of the verse that says "Never tire of doing good, for at the right time you will reap a harvest if we do not give up." (Gal 6:9) Because really, glorifying the Lord is what it is about, if a friend is gained wonderful. But how horrible it would be the miss out of seeing the Lord work b/c I was selfish and wanted something more out of it, isn't the Lords blessing enough? ...A frustrating day, yet a day where frustration turned to perserverance as I chase after the things the Lord has called me to take part in...
