God is omniscient/omnipresent. What does that mean practically speaking?
To those that pray: God indeed hears you! He hears us BEFORE we pray.
To the anxious: God sees you! If you are lying on the battlefield of life, God sees you. he will relieve you, for He only needs to see the woes of His children to relieve them.
To the slandered: God sees you for who you really are so shut out the despairing voices of falsehood. Some may think you guilty, but God knows your innocence.
To those who know not Christ: Whenever you sin, you sin in the presence of God. So repent, for His evidence at the judgment is full proof.
