Rev. 2:23 "I will strike her children dead. And all the churches will know that I am the one who searches out the thoughts and intentions of every person. And I will give to each of you whatever you deserve."
Jesus makes it very clear; He is the one who searches out the thoughts and intentions of every person. Jesus knows what you are thinking all the time. I don't know about you, but there are times in which I wish that the Lord did not know what I was thinking. It's impossible to always keep our thoughts in order. We may not express how we feel, but the Lord knows what is going on in our heads. We need to strive as much as possible to keep our minds focused on that which is good and wholesome so it won't be filled with things that are harmful to our souls.
Jesus makes it clear; He know the intentions of every person. He knows why we do what we do. He knows better than we do why we do things. He looks deep into the soul and understands the direction of our souls and how it affects what we do and say. We can fool one another easy enough, and sometimes even ourselves, but we can never fool the Lord.
Jesus makes it clear; we will get whatever we deserve. God never makes a mistake when He doles out justice. He judges us according to His revealed truth. No one will stand before the Lord and receive from Him more or less than he deserves. This truth can either comfort us or frighten us. We need to live in such a way that we are comforted by this wonderful truth. The Lord is a rewarder of those who are faithful to Him.
