In the year that the supreme commander, sent by Sargon king of Assyria, came to Ashdod and attacked and captured it - at that time the LORD spoke through Isaiah son of Amoz. He said to him, "Take off the sackcloth from your body and the sandals from your feet." And he did so, going around stripped and barefoot. Then the LORD said, "Just as my servant Isaiah has gone stripped and barefoot for three years, as a sign and portent against Egypt and Cush, so the king of Assyria will lead away stripped and barefoot the Egyptian captives and Cushite exiles, young and old, with buttocks bared - to Egypt's shame. (Isaiah 20:1-4)
The obedience of Isaiah is worth noticing here for he did as the Lord said, not caring what people would comment about him. No sackcloth, no sandals.....stripped and barefoot.......
The Lord loves his children who are obedient to him. The Bible speaks at length regarding God asking his people to be obedient.
Regarding Jesus' obedience to the father in heaven, Paul the Apostle writes,
And being found in appearance as a man, he humbled himself and became obedient to death - even death on a cross! (Philippians 2:8)
And the exhortation to believers from Peter the Apostle is....
As obedient children, do not conform to the evil desires you had when you lived in ignorance. (1 Peter 1:14)
Do we really love the Lord? "But Of Course", many believers would say. But our love for the Lord can be tested by our obedience, for the Bible says,
And this is love: that we walk in obedience to his commands. As you have heard from the beginning, his command is that you walk in love. (2 John 1:6)
