2.4-Don't wait until everyone believes in you before you get busy helping people.

2.4-
I have read that when Mary had Jesus she was about 14 years old.  I'm not sure.  But I am sure that they didn't think that Jesus had any special training or wisdom and shouldn't be thought of as a teacher.

Mark 6.

6 Jesus left there and went to his hometown, accompanied by his disciples. ² When the Sabbath came, he began to teach in the synagogue, and many who heard him were amazed.

“Where did this man get these things?” they asked. “What’s this wisdom that has been given him? What are these remarkable miracles he is performing? ³ Isn’t this the carpenter? Isn’t this Mary’s son and the brother of James, Joseph,^[a] Judas and Simon? Aren’t his sisters here with us?” And they took offense at him.
⁴ Jesus said to them, “A prophet is not without honor except in his own town, among his relatives and in his own home.” ⁵ He could not do any miracles there, except lay his hands on a few sick people and heal them. ⁶ He was amazed at their lack of faith.

Then Jesus went around teaching from village to village. ⁷ Calling the Twelve to him, he began to send them out two by two and gave them authority over impure spirits.
⁸ These were his instructions: “Take nothing for the journey except a staff—no bread, no bag, no money in your belts. ⁹ Wear sandals but not an extra shirt. ¹⁰ Whenever you enter a house, stay there until you leave that town. ¹¹ And if any place will not welcome you or listen to you, leave that place and shake the dust off your feet as a testimony against them.”
¹² They went out and preached that people should repent. ¹³ They drove out many demons and anointed many sick people with oil and healed them.
