… Just go with Him

24 Then said Jesus unto his disciples, If any man will come after me, let him deny himself, and take up his cross, and follow me.
25 For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it.
26  For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul?
(Matt. 16:24-26)

You’re at peace now because He’s in charge and He will look after you

26 And when the disciples saw him walking on the sea, they were troubled, saying, It is a spirit; and they cried out for fear.
27 But straightway Jesus spake unto them, saying, Be of good cheer; it is I, be not afraid.
28 And Peter answered him and said, Lord, if it be thou, bid me come unto thee on the water.
29 And he said, Come. And when Peter was come down out of the ship, he walked on the water, to go to Jesus.
30 But when he saw the wind boisterous, he was afraid; and beginning to sink, he cried, saying, Lord, save me.
31 And immediately Jesus stretched forth his hand, and caught him, and said unto him, O thou of little faith, wherefore didst thou doubt?
32 And when they were come into the ship, the wind ceased.
(Matt. 14:26-32)

When you accept that everything that you have belong to Him you can give up worrying about not having everything else and be content to trust Him fully to give you whatever He desires

31 Another parable put he forth unto them, saying, The kingdom of heaven is like to a grain of mustard seed, which a man took, and sowed in his field:
32 Which indeed is the least of all seeds: but when it is grown, it is the greatest among herbs, and becometh a tree, so that the birds of the air come and lodge in the branches thereof.
(Matt. 13:31-32)
