Who are the sons of disobedience? The sons of disobedience comprise two groups of individuals, 1) those who have never believed upon Jesus as their LORD and Savior and 2) those who have believed upon him, but then have turned from following him to a life characterized by disobedience. The second group is described as follows:
I want you to know, brothers, that our fathers were all under the cloud, and all passed through the sea, [2] and all were baptized into Moses in the cloud and in the sea, [3] and all ate the same spiritual food, [4] and all drank the same spiritual drink. For they drank from the spiritual Rock that followed them, and the Rock was Christ. [5] Nevertheless, with most of them God was not pleased, for they were overthrown in the wilderness.
[6] Now these things took place as examples for us, that we might not desire evil as they did. [7] Do not be idolaters as some of them were; as it is written, “The people sat down to eat and drink and rose up to play.” [8] We must not indulge in sexual immorality as some of them did, and twenty-three thousand fell in a single day. [9] We must not put Christ to the test, as some of them did and were destroyed by serpents, [10] nor grumble, as some of them did and were destroyed by the Destroyer. [11] Now these things happened to them as an example, but they were written down for our instruction, on whom the end of the ages has come. [12] Therefore let anyone who thinks that he stands take heed lest he fall. [13] No temptation has overtaken you that is not common to man. God is faithful, and he will not let you be tempted beyond your ability, but with the temptation he will also provide the way of escape, that you may be able to endure it. [14] Therefore, my beloved, flee from idolatry. [15] I speak as to sensible people; judge for yourselves what I say. (1 Cor. 10:1-15 ESV)
The Book of Hebrews deals with this same theme with respect to entering God’s rest:
Therefore, while the promise of entering his rest still stands, let us fear lest any of you should seem to have failed to reach it. [2] For good news came to us just as to them, but the message they heard did not benefit them, because they were not united by faith with those who listened. [3] For we who have believed enter that rest, as he has said,
“As I swore in my wrath,
‘They shall not enter my rest,’ “
although his works were finished from the foundation of the world. [4] For he has somewhere spoken of the seventh day in this way: “And God rested on the seventh day from all his works.” [5] And again in this passage he said,
“They shall not enter my rest.”
[6] Since therefore it remains for some to enter it, and those who formerly received the good news [the Gospel] failed to enter because of disobedience, [7] again he appoints a certain day, “Today,” saying through David so long afterward, in the words already quoted,
“Today, if you hear his voice,
do not harden your hearts.”
[8] For if Joshua had given them rest, God would not have spoken of another day later on. [9] So then, there remains a Sabbath rest for the people of God, [10] for whoever has entered God’s rest has also rested from his works as God did from his.
[11] Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience. [12] For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart. [13] And no creature is hidden from his sight, but all are naked and exposed to the eyes of him to whom we must give account.
[14] Since then we have a great high priest who has passed through the heavens, Jesus, the Son of God, let us hold fast our confession. [15] For we do not have a high priest who is unable to sympathize with our weaknesses, but one who in every respect has been tempted as we are, yet without sin. [16] Let us then with confidence draw near to the throne of grace, that we may receive mercy and find grace to help in time of need. (Hebrews 4:1-16 ESV)
Hebrews teaches us that we enter God’s rest by “holding fast our confession.” This means that we come into agreement with Jesus with respect to all things. When our conscience convicts us of wrongdoing, we confess our sins to our High Priest who intercedes for us and keeps us pure before God. In this way we remain pure and obedient before him. As sons of God we remain sons of obedience.
Sons of disobedience do not wash themselves in the water of Christ’s word. They do not understand nor walk in his ways. Thus they walk in lawlessness. They insist on calling good evil and evil good because they do not know God. Therefore they cannot confess their sins and cannot continually cleanse themselves before him at the his altar, the altar of Melchizedek.
And you were dead in the trespasses and sins [2] in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience… (Ephesians 2:1-2 ESV)
“Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience.” (Ephesians 5:6 ESV)
Therefore let us strive to enter God’s rest by coming to know our God and practicing his righteousness.
