This verse encourages me, so much, that all the times I choose to do good and deny myself, I am storing up treasures in heaven and I will reap the benefits. Sometimes I get tired of doing "good" all the time. I just feel like yelling at my sibilings, being lazy, or talking back to my parents, but instead I choose to do good. Sometimes I reap the benefits in a couple of hours. For example when I have finished my school right away instead of being lazy I can go hang out with my dad and hang tree stands in the afternoon. Also sometimes it can take years to reap the benefits of doing good. For example when I am patient and don't yell at my sibilings when they want my help for school, I loose time in my day and do not reap any benefits right away. Though now that my sister and brother are in highschool it is so nice to see that they get concepts that I helped explain in their earlier years. It took a couple years to reap the benefits, but it was definently worth it. An even greater bonus is we have a loving relationship that I could have easily squashed if I would have chosen to be selfish.
I think this verse alsoapplies to parenting as well, it is so easy for a mom to get angry when a child acts up or not want to train their kids to sit still, again. But if the parents stick it out they will reap the benefits in the end. I am so glad that my parents stuck through with me and because they did, not only are they reaping the benefits, but I am also; because they took the time to train me in love. My parents have put a lot of trust in me. A few times I have thought about doing something they wouldn't have approved of, but never for very long because I don't want to loose the benefit of trust that they have given me; built because I have not grown weary of doing good.
I just want to encourage you as parents and as fellow Christian's not to give up doing good, but instead look forward to the harvest and keep up the good work. Afterwords when you are able to reap the rewards you will be so thankful that you stuck with it and your children will thank you also.
