Jesus said to his disciples:
For you do not know on which day your Lord will come.
Be sure of this:
if the master of the house
had known the hour of night when the thief was coming,
he would have stayed awake
and not let his house be broken into.
So too, you also must be prepared,
for at an hour you do not expect, the Son of Man will come."
I read somewhere that this pertains to when we die, for we know not when we will be called home. And not necessarily about the second coming of Christ. But I can actually tell you this is true. This may have to do with how well we keep our hearts clean from sin.
Should God decide to come and pay your heart a visit at any given moment, what will he encounter? I know there is this other, that God dwells within us always, but what happens when we push him out, or crowd him out of his home within us. What happens when he tries to reenter into the dwelling that pushed him out, what will he find. Room to live, or far more clutter than before.
What about those who never knew him at all, and he comes to pay your heart a visit, so he can make his home within, will he find it empty or full. There are so many scenarios to envision how well we keep our hearts clean.
Since I did have the grace to encounter the Spirit of God, walk through and feel his presence on my eyes and know of the most beautiful voice ever to hear, in the early morning hours. Then I can say for a fact He did come and found my heart empty of sin. What Jesus tells us in this reading is so true, will he find our hearts empty and ready for him. Or are we busy keeping it cluttered, instead of sweeping out the useless junk we have collected.
As Jesus puts it, stay awake, be vigilant, "So too, you also must be prepared, for at an hour you do not expect, the Son of Man will come." And this is so very true.
