Gain through giving?

I once heard it said, that the reason we give so much up in our lives for other people is because they are what we leave behind when we are gone, through them our lives continue. It sounds a little strange until you think about it. When I mention a ‘but God’ moment, it’s my poppa speaking through me, when I struggle and find myself putting scripture in my shoes so all day I am standing on the word of God, that’s my nana. Those who are gone leave their legacy in us, and if they hadn’t taken the time and effort to teach me, serve me and be with me I might not have the strength that their words gave me. Nana is gone to Heaven but she still lives and guides and teaches through all the people she put effort into. We live in a ‘serve yourself first and then you will have the strength to serve others’ theory in this world, even evangelist speakers have said this once in awhile, and not that serving yourself is wrong, but if the only one you serve is yourself then that is wrong. Jesus didn’t say ‘love yourself, that is the greatest commandment,’ He said ‘love the Lord your God, and your neighbour as yourself.’ If all we ever do is serve us we miss out on the true Joy of serving others and through serving others serving God. Our joy comes from fellowship with Christ, you cannot serve yourself only and have fellowship with others. This sounds really discouraging I know, but I’m not saying drop everything and give up all your time for others, I mean we should actively aim and strive to be servants. If you want to spend a day sitting on the couch watching TV that’s fine, but if while sitting on that couch somebody calls you in need and you refuse to go because you’re busy taking care of yourself isn’t that wrong? As in all things there’s a balance, you can’t only serve others because you’ll hit burnout, but you can’t only serve yourself because that’s not how Christians Act. It always comes back to the old adage, what would Jesus do? Would he say no cuz he was too busy taking care of himself? Or would He go to help those in need? I guess that’s a dumb question, considering the answer is so obvious.
