James 5:12
12 But most of all, my brothers and sisters, never take an oath, by heaven or earth or anything else. Just say a simple yes or no, so that you will not sin and be condemned.
Jesus said, "Come, follow me, and I will show you how to fish for people!" Mark 1:17 (NLT)
5 One day as Jesus was preaching on the shore of the Sea of Galilee, great crowds pressed in on him to listen to the word of God. 2 He noticed two empty boats at the water’s edge, for the fishermen had left them and were washing their nets. 3 Stepping into one of the boats, Jesus asked Simon, its owner, to push it out into the water. So he sat in the boat and taught the crowds from there.
4 Then Jesus, full of the Holy Spirit, returned from the Jordan River. He was led by the Spirit in the wilderness, 2 where he was tempted by the devil for forty days. Jesus ate nothing all that time and became very hungry.
