Decades later, there will come a time when you will be holding your aged parents' hands and regret, "I should have served you more while I could."
It is good to serve your parents now thinking about that day which will surely come
But, if that day did come before you have no regret, then, you still could say, "I will serve you God, with my added dedication and heart of serving my parents."
Then, your love for your parents and your love for God deeply connects towards the end, which is something you could not buy with money
Where is that chance?
Yes, right here and right now!
