One of the funniest things I've ever seen a kid do is put their hands over their eyes when I've told them to hide. After a couple of seconds of wondering what the kid was doing, I realized that this kid thought that by covering their eyes I was unable to see them. You'd think that the more we grow, the more we’d come to understand that this method of hiding just doesn't work. Sadly, a lot of us do the exact same thing; we act as if God cannot see us because we cannot see Him.
Because of this, it is easy to go through with a sin that we think nobody will know about. For example, let's say you're home alone and you know nobody is coming over for a while so you get on the internet and view things you shouldn't. Or maybe you're with a group of people that don't have the same morals as you and you stay with them and, because you don't have anybody around that will have a problem with what you are doing, you do the bad things they are doing.
No matter the situation, if we are all alone and under pressure to sin, we must not forget that God is always with us and He is always watching us. If we act as if He isn't there, then how can we truly say that we have faith in Him? For if "faith is being sure of what we hope for and certain of what we do not see" (Hebrews 11:1), then certainly we would act as if God was watching... right?
When we do things we know we shouldn't, we are showing a lack of respect for God. We all struggle with the sins of this world, but we need to be mindful of God's presence in everything that we do. God being everywhere is not a bad thing though! God is always there to help us out of the situations that we get into. He will never leave us and He will always provide a way out (1 Corinthians 10:13).
When you find yourself in a situation where you are being tempted, instead of ignoring the fact that God is there watching, take a hold of His hand and ask Him to lead you through. Follow Him and show Him your love by doing what you know is right. You will find that, by acknowledging His presence and doing what is good in His sight, you're life will reflect His will and you will be rewared (Romans 2:7).
