Jesus said, ‘You must love the Lord your God with all your heart, with all your soul, and with all your mind. This is the greatest and the first commandment. The second resembles it: You must love your neighbour as yourself.
Why is the command to love God the first command? It isn't because he needs anything from us. Why should adults secure their own oxygen masks in an airplane emergency before helping others? Because if we're not alright, we're no good to others. To love God above anything with everything we've got is to get our ideals right, to set a real foundation for what our life will be about. First off, what is truth? Next, what does it truly mean to love? Knowing God will teach us that because God is Truth and God is Love. Truth is reasonable, so it is not whimsical, and can be grasped with or reason. Truth can be objectively known, and is not subject to contradictory opinion. Truth can be tested, and is a necessary foundation for everything else that follows. And Love.. Love is a verb. It does not rely on arbitrarily changing moods and emotions. It is to will the good of someone else, and act accordingly. It is not self-seeking, for if everyone loves like that, then we are reduced to beasts.
Let's get back to basics. If we don't build our lives on God, anything we build will come to absolutely nothing.
