A person asked me why when someone passes you can feel a presence.
I put it this way, because I know the work of the enemy when others are seeking.
When born you are assigned two angels, they know when the father instructs what they need to do.
And when your heart is grieving its not the person, I believe you are sensing their presence. To comfort and support your need for it.
Think about it, does not this explanation make more sense if you believe.
