Matthew 9

21 Jesus asked the boy’s father, “How long has this been with him?” “From childhood,” he said. 22 “It often throws him into the fire or into the water, trying to kill him. But if You can do anything, have compassion on us and help us.” 23 “If You can?” echoed Jesus. “All things are possible to him who believes!” 24 Immediately the boy’s father cried out, “I do believe; help my unbelief!”

Mark 8

34 Then Jesus called the crowd to Him along with His disciples, and He told them, “If anyone wants to come after Me, he must deny himself and take up his cross and follow Me. 35 For whoever wants to save his life will lose it, but whoever loses his life for My sake and for the gospel will save it.

Mark 6

47 When evening came, the boat was in the middle of the sea, and Jesus was alone on land. 48 He could see that the disciples were straining to row, because the wind was against them. About the fourth watch of the night, Jesus went out to them, walking on the sea. He intended to pass by them, 49 but when they saw Him walking on the sea, they cried out, thinking He was a ghost— 50 for they all saw Him and were terrified.But Jesus spoke up at once: “Take courage! It is I. Do not be afraid.” 51 Then He climbed into the boat with them, and the wind died down. And the disciples were utterly astounded, 52 for they had not understood about the loaves, but their hearts had been hardened.
