John 14:11-14 (New International Version)
11 Believe me when I say that I am in the Father and the Father is in me; or at least believe on the evidence of the works themselves. 12 Very truly I tell you, whoever believes in me will do the works I have been doing, and they will do even greater things than these, because I am going to the Father. 13 And I will do whatever you ask in my name, so that the Father may be glorified in the Son. 14 You may ask me for anything in my name, and I will do it.
Mark 10:46-52 (New International Version)
Blind Bartimaeus Receives His Sight
46 Then they came to Jericho. As Jesus and his disciples, together with a large crowd, were leaving the city, a blind man, Bartimaeus (which means “son of Timaeus”), was sitting by the roadside begging. 47 When he heard that it was Jesus of Nazareth, he began to shout, “Jesus, Son of David, have mercy on me!”
48 Many rebuked him and told him to be quiet, but he shouted all the more, “Son of David, have mercy on me!”
49 Jesus stopped and said, “Call him.”
So they called to the blind man, “Cheer up! On your feet! He’s calling you.” 50 Throwing his cloak aside, he jumped to his feet and came to Jesus.
51 “What do you want me to do for you?” Jesus asked him.
The blind man said, “Rabbi, I want to see.”
52 “Go,” said Jesus, “your faith has healed you.” Immediately he received his sight and followed Jesus along the road.
