These are some texts in Mark that show Jesus and the disciples taking time away from others to be with God.
12 At once the Spirit sent him out into the wilderness, 13 and he was in the wilderness forty days, being tempted by Satan. He was with the wild animals, and angels attended him.
35 Very early in the morning, while it was still dark, Jesus got up, left the house and went off to a solitary place, where he prayed. 36 Simon and his companions went to look for him, 37 and when they found him, they exclaimed: “Everyone is looking for you!”
38 Jesus replied, “Let us go somewhere else—to the nearby villages—so I can preach there also. That is why I have come.” 39 So he traveled throughout Galilee, preaching in their synagogues and driving out demons.
7 Jesus withdrew with his disciples to the lake, and a large crowd from Galilee followed. 8 When they heard about all he was doing, many people came to him from Judea, Jerusalem, Idumea, and the regions across the Jordan and around Tyre and Sidon. 9 Because of the crowd he told his disciples to have a small boat ready for him, to keep the people from crowding him. 10 For he had healed many, so that those with diseases were pushing forward to touch him. 11 Whenever the impure spirits saw him, they fell down before him and cried out, “You are the Son of God.” 12 But he gave them strict orders not to tell others about him.
13 Jesus went up on a mountainside and called to him those he wanted, and they came to him. 14 He appointed twelve that they might be with him and that he might send them out to preach 15 and to have authority to drive out demons. 16 These are the twelve he appointed: Simon (to whom he gave the name Peter), 17 James son of Zebedee and his brother John (to them he gave the name Boanerges, which means “sons of thunder”), 18 Andrew, Philip, Bartholomew, Matthew, Thomas, James son of Alphaeus, Thaddaeus, Simon the Zealot 19 and Judas Iscariot, who betrayed him.
35 That day when evening came, he said to his disciples, “Let us go over to the other side.” 36 Leaving the crowd behind, they took him along, just as he was, in the boat. There were also other boats with him. 37 A furious squall came up, and the waves broke over the boat, so that it was nearly swamped. 38 Jesus was in the stern, sleeping on a cushion. The disciples woke him and said to him, “Teacher, don’t you care if we drown?”
39 He got up, rebuked the wind and said to the waves, “Quiet! Be still!” Then the wind died down and it was completely calm.
40 He said to his disciples, “Why are you so afraid? Do you still have no faith?”
41 They were terrified and asked each other, “Who is this? Even the wind and the waves obey him!”
45 Immediately Jesus made his disciples get into the boat and go on ahead of him to Bethsaida, while he dismissed the crowd. 46 After leaving them, he went up on a mountainside to pray.
47 Later that night, the boat was in the middle of the lake, and he was alone on land. 48 He saw the disciples straining at the oars, because the wind was against them. Shortly before dawn he went out to them, walking on the lake. He was about to pass by them, 49 but when they saw him walking on the lake, they thought he was a ghost. They cried out, 50 because they all saw him and were terrified.
Immediately he spoke to them and said, “Take courage! It is I. Don’t be afraid.” 51 Then he climbed into the boat with them, and the wind died down. They were completely amazed, 52 for they had not understood about the loaves; their hearts were hardened.
53 When they had crossed over, they landed at Gennesaret and anchored there. 54 As soon as they got out of the boat, people recognized Jesus. 55 They ran throughout that whole region and carried the sick on mats to wherever they heard he was. 56 And wherever he went—into villages, towns or countryside—they placed the sick in the marketplaces. They begged him to let them touch even the edge of his cloak, and all who touched it were healed.
24 Jesus left that place and went to the vicinity of Tyre. He entered a house and did not want anyone to know it; yet he could not keep his presence secret. 25 In fact, as soon as she heard about him, a woman whose little daughter was possessed by an impure spirit came and fell at his feet. 26 The woman was a Greek, born in Syrian Phoenicia. She begged Jesus to drive the demon out of her daughter.
27 “First let the children eat all they want,” he told her, “for it is not right to take the children’s bread and toss it to the dogs.”
28 “Lord,” she replied, “even the dogs under the table eat the children’s crumbs.”
29 Then he told her, “For such a reply, you may go; the demon has left your daughter.”
30 She went home and found her child lying on the bed, and the demon gone.
2 After six days Jesus took Peter, James and John with him and led them up a high mountain, where they were all alone. There he was transfigured before them. 3 His clothes became dazzling white, whiter than anyone in the world could bleach them. 4 And there appeared before them Elijah and Moses, who were talking with Jesus.
5 Peter said to Jesus, “Rabbi, it is good for us to be here. Let us put up three shelters—one for you, one for Moses and one for Elijah.” 6 (He did not know what to say, they were so frightened.)
7 Then a cloud appeared and covered them, and a voice came from the cloud: “This is my Son, whom I love. Listen to him!”
8 Suddenly, when they looked around, they no longer saw anyone with them except Jesus.
9 As they were coming down the mountain, Jesus gave them orders not to tell anyone what they had seen until the Son of Man had risen from the dead. 10 They kept the matter to themselves, discussing what “rising from the dead” meant.
11 And they asked him, “Why do the teachers of the law say that Elijah must come first?”
12 Jesus replied, “To be sure, Elijah does come first, and restores all things. Why then is it written that the Son of Man must suffer much and be rejected? 13 But I tell you, Elijah has come, and they have done to him everything they wished, just as it is written about him.”
32 They went to a place called Gethsemane, and Jesus said to his disciples, “Sit here while I pray.” 33 He took Peter, James and John along with him, and he began to be deeply distressed and troubled. 34 “My soul is overwhelmed with sorrow to the point of death,” he said to them. “Stay here and keep watch.”
35 Going a little farther, he fell to the ground and prayed that if possible the hour might pass from him. 36 “Abba, Father,” he said, “everything is possible for you. Take this cup from me. Yet not what I will, but what you will.”
37 Then he returned to his disciples and found them sleeping. “Simon,” he said to Peter, “are you asleep? Couldn’t you keep watch for one hour? 38 Watch and pray so that you will not fall into temptation. The spirit is willing, but the flesh is weak.”
39 Once more he went away and prayed the same thing. 40 When he came back, he again found them sleeping, because their eyes were heavy. They did not know what to say to him.
41 Returning the third time, he said to them, “Are you still sleeping and resting? Enough! The hour has come. Look, the Son of Man is delivered into the hands of sinners. 42 Rise! Let us go! Here comes my betrayer!”
