Why did Jesus choose Judas to sit with Him?

In the context of the Last Supper, Judas Iscariot, despite being one of the twelve apostles, illustrates the complexity of God's sovereign election. Jesus acknowledges that Judas' presence was essential to fulfill Scripture, as noted in John 17, where He speaks of the 'son of perdition.' This reveals the reality that God allowed Judas to partake, signifying both His sovereignty and the existence of tares among the wheat in the church. The scripture teaches us that even those appearing to be part of the flock can be devoid of true faith.
