Just as all objects of the world have the universal law of gravitation that pulls on each other, the farther we grow apart from God, the weaker our spiritual power becomes and the more our faith cools down.
However, the closer we come to God, the more powerful our spiritual power of the Holy Spirit becomes.

Satan makes the world more evil and lustful to stop us from coming closer to God and creates an environment that makes people leave God’s commands and do evil.
