I don't think I am at odds with you, they are so closely related that the tandem cannot be easily separated, and thus, pragmatically, they are often interchangeable. There is a distinction between the two, however, and obedient action is the logical offspring of belief in Christ being exercised. Being obedient is the outward expression and thus visible proof of our belief!

Yes, it's clear they are different words & have different meanings. I'm probably a bit tighter than you at the moment, the way I understand you. I think
obedient action is faith in action.
The logic of being commanded to believe, or being commanded to love (as another example), leaves me with the understanding that we really cannot believe or love Biblically without being obedient. God has simply structured it this way and covered these vital things with commands.
Re: the differentiation, there are times when
our Lord did emphasize one over the other - thereby differentiating them. When His disciples failed Him at times He called them "little faiths" - emphasizing faith. And I'm going to throw this one at you for consideration of another time when His disciples want to make it a matter of needing more faith and He seems to just tell them to do what He commands - emphasizing obedience:
NKJ Lk. 17:3-9 "Take heed to yourselves. If your brother sins against you, rebuke him; and if he repents, forgive him. 4 "And if he sins against you seven times in a day, and seven times in a day returns to you, saying,`I repent,' you shall forgive him." And the apostles said to the Lord, "
Increase our faith." 6 So the Lord said, "If you have
faith as a mustard seed, you can say to this mulberry tree,`Be pulled up by the roots and be planted in the sea,' and it would
obey you. 7 "And which of you, having a servant plowing or tending sheep, will say to him when he has come in from the field,`Come at once and sit down to eat '? 8 "But will he not rather say to him,`Prepare something for my supper, and gird yourself and serve me till I have eaten and drunk, and afterward you will eat and drink '? 9 "
Does he thank that servant because he did the things that were commanded him? I think not.
Jesus issues 4 commands here. His disciples seem to think this is a tough task and ask Him to increase their faith. His answer seems to be that this is not about faith and a servant is just to do what his master commands him to do and not even to expect to be thanked for doing it.
For me this just says obedience is expected. Sometimes He'll work on our faith so we'll come to obey. Sometimes He'll just tell us to do what He commands. The core issue of either and both is obedience. Think of all the vital concepts tied to obedience - Love for God is keeping His commandments (obedience) - as JLB has been pointing out: knowing God is keeping His commandments (obedience - and BTW eternal life is knowing God so reason the logic here & see another concept tied to obedience) - Children of God do righteousness & keep God's commandments/love God (obedience). There are many more of these.
Your screen name is TibiasDad, so I assume you're a father. Sometimes we instruct. Sometimes we just tell the child to do what they're told to do. At some point the instruction is imbedded and the task is just done naturally (at least with God's Children as we looked at recently). Think laws written on hearts, trained consciences, obedience ultimately being natural.
So, you're right, of course, they are different. And both need to be developed to work properly.
But I think the overlap is supposed to be 100% and I think this is what the Scriptures I gave you are showing us (this is probably my main point, as I don't think I need to convince of the importance of obedience). While being developed, sometimes we need our faith to be strengthened, and sometimes we just need to do what we're told.
In the end with His perfect parenting and disciplinary training, Faith-Obedience becomes the grown-up condition. And Faith-Obedience, when you reason this through enough, just seems to blend into one word - Faithful - sons of faithful Abraham - and siblings of our faithful first-born Brother & Lord.
NKJ Hebrews 3:1-2 Therefore, holy brethren, partakers of the heavenly calling, consider the Apostle and High Priest of our confession,
Christ Jesus, 2 who was faithful to Him who appointed Him, as Moses also was
faithful in all His house.
That's my take.
