It does sound somewhat funny to hear you say, I'm taking those verses out of context, because it works for me even as I described how it works.
You say, "God isn't a genie or waiter", but His word is, and more.
I will explain that later.
Let's look at those verses again, only I will expound on them some.
Rom 10:8 But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach;
Rom 10:9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
Rom 10:10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
Verse 8 explains what word of faith is and how it works.
Verses 9 and 10 are examples of what verse 8 describes or explains word of faith is.
Verses 9 and 10 are indeed talking about salvation, but notice how those verses show just how word of faith works as it is written in verse 8?
Word of faith is a law, and it doesn't just work for salvation.
If I remove the rest of the sentence of each verse, it shows some similarities in each verse.
Rom 10:8 in thy mouth
in thy heart
Rom 10:9 if thou shalt confess with thy mouth
shalt believe in thine heart
Rom 10:10 with the heart man believeth unto
with the mouth confession is made unto
Jesus put it this way.
Mar 11:23
For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith.
The above verse is pretty simple and strait forward to understand what is being said.
Does it matter what Jesus was talking about?
Not really, but to keep it in context, Jesus not only was explaining to Peter HOW He caused the fig tree to die, but also how anyone with the faith of God or "whosoever" speaks to whatsoever without doubting in their heart, it will be done for them even as it was done for Jesus.
Again, faith is a law.
Paul called it the law of faith.
It works the same as the law of gravity, and just as consistent.
I told you I would explain about the word of God being our servant, and below gives you examples
Mat 8:5 And when Jesus was entered into Capernaum, there came unto him a centurion, beseeching him,
Mat 8:6 And saying, Lord, my servant lieth at home sick of the palsy, grievously tormented.
Mat 8:7 And Jesus saith unto him, I will come and heal him.
Mat 8:8 The centurion answered and said, Lord, I am not worthy that thou shouldest come under my roof: but
speak the word [of faith] only, and
my servant shall be healed.
Now the centurion is about to explain and compare how he sees Jesus' word of authority and power, to his own.
Mat 8:9 For I am a man under authority, having soldiers under me: and
I say to this man, Go, and he goeth; and to another, Come, and he cometh; and to my servant, Do this, and he doeth it.
Mat 8:10
When Jesus heard it, he marvelled, and said to them that followed, Verily I say unto you,
I have not found so great faith, no, not in Israel.
Mat 8:11 And I say unto you, That many shall come from the east and west, and shall sit down with Abraham, and Isaac, and Jacob, in the kingdom of heaven.
Mat 8:12 But the children of the kingdom shall be cast out into outer darkness: there shall be weeping and gnashing of teeth.
Mat 8:13 And
Jesus said unto the centurion, Go thy way; and as thou hast believed, so be it done unto thee. And his servant was healed in the selfsame hour.
Jesus again used the word of faith when He spoke what He believed in His heart.
What made Jesus marvel at the centurion?
It was that he saw something no one else did.
That being, the word of faith was both sent and subject to Jesus, even as the centurion's servants and soldiers under him were subject to him.
Point being, the word of God is as a servant or soldier to the sender, and it is the word itself that does the work, even as a servant or soldier does the work he/she was sent to do.
Again, we have yet another example of the word of faith, based on the promises of God, compared to a servant.
Luk 17:5 And the apostles said unto the Lord, Increase our faith.
Luk 17:6 And the Lord said,
If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree
[or whatsoever], Be thou plucked up by the root, and be thou planted in the sea; and
it should obey you.
What should obey you, the thing you spoke to or the word you just sent?
Is the object subject to us or the word of faith?
He explains with a parable.
Unworthy Servants
Luk 17:7 But
which of you,
having a servant plowing or feeding cattle, will say unto him by and by, when he is come from the field, Go and sit down to meat?
Luk 17:8 And will not rather
say unto him, Make ready wherewith I may sup, and gird thyself, and serve me, till I have eaten and drunken; and afterward thou shalt eat and drink?
Luk 17:9
Doth he thank that servant because he did the things that were commanded him? I trow not.
Luk 17:10
So likewise ye, when ye shall have done all those things which are commanded you, say, We are unprofitable servants: we have done that which was our duty to do.
The word of God, spoken in faith, is the one who does the work it was sent and ordered to do.
Who or what created the worlds and all that is in it?
Heb 11:3 We understand that the worlds were framed by the word of God, through faith, so that things which are seen were not made of things which do appear.
I changed the order around a little for clarity sake.
What the above verse is saying is that the world were made BY the word of God itself.
Are we not allowed to speak God's word boldly, in faith.
Are we not suppose to remind God, what He said.
Are we not suppose to thank, praise, and worship Him, believing He is faithful who promised and that He will not only watch over and hasten to perform His word, through and by His word?
And should we not believe that His word should not return to us void, but accomplish that which we please, and prosper in the thing whereto WE SENT IT?
After all, in Psa 103:20 even his angels, excel in strength, that do his commandments,
hearkening unto the voice of his word [OR TO THOSE WHO SPEAK FORTH, OR GIVE VOICE TO, HIS WORD].
It is all about the word of God, which is a seed or offspring of God, doing what we send it to do, knowing it will accomplish what it was sent to do.
Just like the servant in the parable.
