O LORD, thou hast searched me, and known me.
Thou knowest my downsitting and mine uprising, thou understandest my thought afar off.
Thou compassest my path and my lying down, and art acquainted with all my ways.
For there is not a word in my tongue, but, lo, O LORD, thou knowest it altogether.
Source: Psalm 139:1-4
Note: We have some in society who think that no one is smart enough to know what their true thoughts are. As humans we can't actually know what another individual is thinking, even when they say they like us but their attitude tells a different story. If a person say they like you, but they say mean things about you, that's not like.
There are those who practice behavior that is questionable while claiming to love the Lord. God knows every thought we each have. The person who say they like someone, yet they don't; God judge such individual to be a liar. He knows our plans and has the power to stop us or to allow us to succeed.If our plan is to harm someone without needing to defend our life or an innocent person, then we must prepare ourselves to receive his judgment. Asking God for forgiveness in this situation will not prevent him from punishing such an individual. When we anger God, it put at risk other individuals. We have to understand, Supernatural Power is unlike any other power.
