What does it mean to abide in him?

As God's first born children left Egypt, the Egyptians were moved by the spirit of God to give them Gold,  and Jewels, and precious things. The Chosen's hearts became inflamed.  So instead of worshiping God, they turned towards a New God: the Golden Calf.  Working with their newly acquired Gold they attempted to supplant God with a God they could see and worship in their newly formed.  They deemed the Golden Calf more worthy than a God they could not envision.

 Jesus received a blessing of anointment from his father when John baptized him in the Jordan.  Jesus was tempted right afterwards for forty days in the desert by the Devil.  But instead of creating food from stone, or throwing himself off of the top of the temple, or claiming what was already his; he abide in the LORD.
Jesus walked under the shadow of God to illustrate God's enduring Love: love that does not change,  lasts forever, and  provides enough to eat when times are tough.

We are chosen to be stewards of a kingdom that is not yet complete but has already been redeemed.  We must turn to the LORD and repent for a Heavenly Kingdom is near.
