I believe that as a Christian it's easy to think that God has briefly forgotten about us. There have been many times in my life where I have done good things over and over again and it never seemed like there was a payoff. I felt like nobody noticed what I was doing. I felt good about it because I knew I was living obediently, but there certainly wasn't much significance in the way that I was feeling.
During those times I was under the impression that I was supposed to receive some sort of positive affirmation from others. God never forgets about us. But Satan deceives us into thinking that by trying to make us worry about the recognition we receive from others vs. always being recognized by God.
Sometimes I just think about certain ways in which God calls us to live. We are commanded to love one another. Well sometimes when I am loving everyone around me I don't really feel like anyone is noticing it. That is a feeling that comes from Satan because we serve a God who is not unjust.
It's crazy to me that we get worried about others not noticing the good we do when the one person who will always remember always notices the work that we are doing. Our minds are so easily twisted...
God is not unjust; he will not forget your work and the love you have shown him as you have helped his people and continue to help them. (Hebrews 6:10)
I know it might seem like it sometimes because we are easily deceived but God will never forget or overlook our hard work for him. Presently you may not be receiving rewards and acclaim, but God knows your efforts of love and ministry. Let God's love for you and his intimate knowledge of your service for him bolster you as you face disappointment and rejection here on earth.
Your hard work is never forgotten so please don't ever be discouraged. Keep on pushing!
