When the Israelites sinned, they did so “in the sight of the Lord.” Of course, there is no other place we can sin. Everything we do is in plain sight of heaven. God sees everything.
From the dawn of mankind, people have been convinced that their sinful actions were somehow concealed from their Maker. We tend to treat God as if He were merely another person. We act as if we can hide our actions from Him, just as we can covertly sin without others knowing what we are doing (at least for a time). But God is not like other people. He is God. He not only knows what we do, He is also aware of what we say and think. There is no fooling God. All of the evidence of our sin lies before Him.
There is no point in arguing our innocence before God. It is futile to claim that God is being unfair to us or overly harsh. Rather, God shows remarkable restraint in meting out punishment to us, considering He has irrefutable evidence of our apostasy ever before Him.
Before you continue about your day, consider the fact that whatever you do today will be fully in the sight of God. Live accordingly.
