When we’re taught things and they are repeated to us over and over again, or we put into action what we’ve been taught, we are far more likely to remember it.
When it comes to loving one another, the same applies. That’s why the bible tells us that right from the beginning, we are told to love one another:
For this is the message you heard from the beginning: We should love one another. ~ 1 John 3:11 NIV
Even if you haven’t ben told to love one another, right from the beginning of your life, it’s not too late to love everyone.
