5 Bondservants, be obedient to those who are your masters according to the flesh, with fear and trembling, in sincerity of heart, as to Christ
Ephesians 6: 5
Obedience is more than just believing.
12 Therefore, my beloved, as you have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling
Philippians 2:12
St. Paul said this to “believers” who already had “faith.”
19 Then His mother and brothers came to Him, and could not approach Him because of the crowd.
20 And it was told Him by some, who said, “Your mother and Your brothers are standing outside, desiring to see You.”
21 But He answered and said to them, “My mother and My brothers are these who hear the word of God and do it.”
Luke 8: 19-21
Notice Jesus didn’t say "My mother and My brothers are these who hear the word of God and “have faith in it.” Jesus says something even stronger in Matthew’s Gospel:
23 "And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’
24 "Therefore whoever hears these sayings of Mine, and does them, I will liken him to a wise man who built his house on the rock:
25 "and the rain descended, the floods came, and the winds blew and beat on that house; and it did not fall, for it was founded on the rock.
26 "But everyone who hears these sayings of Mine, and does not do them, will be like a foolish man who built his house on the sand:
Matthew 7: 23-26
Notice, Jesus does not say “But everyone who hears these sayings of Mine and has faith in them…” But if you’re still not convinced, Jesus goes on further in the Gospel of Luke:
46 "But why do you call Me ‘Lord, Lord,’ and do not do the things which I say?
47 "Whoever comes to Me, and hears My sayings and does them, I will show you whom he is like:
48 "He is like a man building a house, who dug deep and laid the foundation on the rock. And when the flood arose, the stream beat vehemently against that house, and could not shake it, for it was founded on the rock.
49 “But he who heard and did nothing is like a man who built a house on the earth without a foundation, against which the stream beat vehemently; and immediately it fell. And the ruin of that house was great.”
Luke 6: 46-49
Notice in verse 46 Jesus didn’t say “But why do you call Me Lord, Lord, and do not fave faith…” Jesus goes on to gives us specific examples of how we should live our lives. He also specified, that by living our lives in way that Christ taught us, we become His neighbors.
29 But he, wanting to justify himself, said to Jesus, “And who is my neighbor?”
30 Then Jesus answered and said: "A certain man went down from Jerusalem to Jericho, and fell among thieves, who stripped him of his clothing, wounded him, and departed, leaving him half dead.
31 "Now by chance a certain priest came down that road. And when he saw him, he passed by on the other side.
32 "Likewise a Levite, when he arrived at the place, came and looked, and passed by on the other side.
33 "But a certain Samaritan, as he journeyed, came where he was. And when he saw him, he had compassion.
34 "So he went to him and bandaged his wounds, pouring on oil and wine; and he set him on his own animal, brought him to an inn, and took care of him.
35 "On the next day, when he departed, he took out two denarii, gave them to the innkeeper, and said to him, ‘Take care of him; and whatever more you spend, when I come again, I will repay you.’
36 “So which of these three do you think was neighbor to him who fell among the thieves?”
37 And he said, “He who showed mercy on him.” Then Jesus said to him, “Go and do likewise.”
Luke 10: 29-37
14 "You are My friends if you do whatever I command you.
John 15: 14
And if that was not enough, it is stressed again just a few verses later:
17 "These things I command you, that you love one another.
John 15: 17
However, if one feels that this is all a misinterpretation of the teaching of Christ, and the teaching of St. Paul, perhaps we need clarification from St. Paul:
17 "But if, while we seek to be justified by Christ, we ourselves also are found sinners, is Christ therefore a minister of sin? Certainly not!
18 "For if I build again those things which I destroyed, I make myself a transgressor.
Galatians 2:17-18
Christ died for our sins, and through Baptism we died with Him (Romans 6:4, Colossians 2:12). If He is to live in us and we in Him (John 14:20, 15:4, 17:21), it is an invitation to a life of holiness:
48 "Therefore you shall be perfect, just as your Father in heaven is perfect.
Matthew 5:48
I will also submit to you that sound doctrine, like salvation through faith and works, as presented above, must be defended as a teaching of Christ. In fact, St. Paul warned Timothy, his Bishop, of this very issue:
1 I charge you therefore before God and the Lord Jesus Christ, who will judge the living and the dead at His appearing and His kingdom:
2 Preach the word! Be ready in season and out of season. Convince, rebuke, exhort, with all longsuffering and teaching.
3 For the time will come when they will not endure sound doctrine, but according to their own desires, because they have itching ears, they will heap up for themselves teachers;
4 and they will turn their ears away from the truth, and be turned aside to fables.
5 But you be watchful in all things, endure afflictions, do the work of an evangelist, fulfill your ministry.
2 Timothy 4:1-5
