“Speak to the people of Israel, When a man or woman commits any of the sins that people commit by breaking faith with the LORD, and that person realizes his guilt, Numbers 5:6 (ESV)
If we break faith with God it is itself a sin and leads unto more sin, it is like a type of adultery to turn our backs on the Lord and withdraw our trust from him
Jesus, knowing that the Father had given all things into his hands, and that he had come from God and was going back to God, John 13:3 (ESV)
Jesus knowing who he is, where he has come from and is going makes his humble act of service even more remarkable. Jesus even washed Judas feet. This displayed his love and gave us an example to follow
I am not speaking of all of you; I know whom I have chosen. But the Scripture will be fulfilled, ‘He who ate my bread has lifted his heel against me.’ John 13:18 (ESV)
Jesus choose Judas to be a disciple knowing all things, including that Judas would choose to betray him regardless of all the love shown to him by Jesus. This shows that someone being called or chosen for ministry or used for Gods purpose does not equate to or guarantee that person has been elected to eternal salvation
All my enemies shall be ashamed and greatly troubled; they shall turn back and be put to shame in a moment. Psalm 6:10 (ESV)
We can use this scripture as we pray for persecuted Christians
