God is present!
When a king or president is in his palace, there is a flag proudly blowing in the wind. That way all who pass, can clearly see that their king or president is present, even though they can't see him in person.
The same way the shining of the stars at night and the sun at day can be seen as a clearly visible sign that God is present, although we can't see Him personally.
So, whenever you think: "Where is God?" Just look around you at all He created.
"For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse"
"The LORD by wisdom hath founded the earth; by understanding hath he established the heavens."
