I am a giver and a doer, it's just who I am. I never expect in return and if I get a "Thank You" then it's nice but I never expect it. My dad was too and I inherited it from him. He taught me to just do my responsibilities and what's expected of me (and usually then some) with no expectations of my own for what I can get out of it. It's the "Jesus Spirit" I think. It's how He manifests himself in me and through me. I guess you could say it's the part of Jesus I identify with. He gave and did himself right into a grave, fighting on my behalf, with no regards as to whether or not I would ever accept it or say Thank You, simply just to make sure it got done. This Easter remember what we are celebrating and why and take a moment to check yourself and make sure you have told Jesus "Thank you!!" If you haven't accepted Him as your saviour it is a simple easy thing to do.
Pray right there where you are "Lord, I am a sinner, I know I can never be worthy on my own but thanks to your sacrifice I can be. I ask you to change my heart and make me new and to fill me with your spirit and your love. Amen."
