When we are going through difficult times( or testing) and still remain obedient to God’s word, we will find, see (the lamb of God) and receive a greater (or deeper) revelation of the lamb of God.
When Abraham was about to offer his only son as a sacrifice, he saw the ram caught in the thicket. He saw the ram take the place of his son. This means he saw Jesus as the sacrificial lamb of God. He received a revelation of Jesus, the lamb of God, as the eternal sacrifice.
When Stephen was persecuted, he saw the glory of God, and Jesus standing at the right hand of God. Jesus at God's right hand signifies that Jesus is coequal with God and has been given sovereign authority to provide or fulfil God's plans on earth. Stephen received a greater revelation of Jesus and his authority.
Two deeper revelations of Jesus Christ were given in testing times when they were obedient to God’s word. Today when you are obedient to God’s word in times of testing, you will see Lamb of God and receive a greater revelation of Jesus Christ.
