When the awe and wonder is still there, there is respect and care as the parties seek to know each other and experience life together. The parties are careful about their interactions.
When that ebbs away, there is less and less initiative from especially the party that has lost the sense of awe, perhaps because that party has found something new to feast his/her attention on.
Maybe because of the fallen nature of mankind. Maybe because of the actions of the other party.
A question comes to mind, how can one retain the x-factor that created the wonder? I have found no better way than to delight oneself in the Lord. His word gives fresh life daily, and one gets something to offer the world.
Without it, one can easily get stuck in a rut of boredom at the core of one’s heart, and be perpetually draining those around them, whether by always being needy or clingy; or carrying a certain dark, gloomy energy, even though it can be hidden behind a flashy-looking exterior.
Without it, one can easily be derailed from the real deal, forget its value and even begin to despise it.
So the key in both cases would be to hide oneself in God, and as God continues to pour in His life, He continue to spread His awe and wonder through us. He draws us more and more to what is profitable, and farther and farther away from what is not. So, help us God.
