Sandals

Then he said, “Do not come near; take your sandals off your feet, for the place on which you are standing is holy ground.”                                                         
                                                     Exodus 3:5

Why did he have to take his sandals off his feet? Receiving a revelation from God is only possible if you have a humble heart. Moses learnt this when he removed his sandals. From that moment he was chosen to serve. The servant is one who serves with all of his heart to please his Lord.
