In my opinion, the presence of God is always with us, it depends on how we feel it. Sometimes others say that they can feel the presence of God when they encounter some minor accident, they say that God is with them because God protecting them from that accident. Or others say that by feeling some cold breeze air while they are walking alone in the middle of the night, so they are not going to be afraid anymore because is with them.
The presence of the Lord is with always all we need to do is Trust God with all our hearts and let God work in our lives.
