Answer
After the return of the seventy disciples who had gone for a mission trip, Jesus responded; C. He rejoiced with them and thanked the Father and B. he turned them into his disciples and said privately, blessed are the eyes which see the things ye see.
Step-by-step explanation
In Luke 10:17 the return of the seventy disciples was a joyful return because the disciples were excited that even the demons submitted to them when they used the name of Jesus Christ to cast them out. Jesus further assured them that because they believed in him then they were made a whole in that Jesus Christ was in them.Thus whoever listened to to the disciples listened directly to Jesus and whoever rejected the disciples, then rejected Him who sent them.
