What is a yoke anyway? It's an old word, "yugom", from Proto-Indo-European times approximately 3700 BC. It's a single ancient language out of which many modern languages are believed to have developed. It has always meant "joined, united" and we get the word subjugated from it.
So we have been asked to do what? We are asked to submit ourselves to the control of God, for Jesus is God. Are we yoked to Jesus? I don't quite read it that way. If we take someone's yoke, we are being subordinate to him, not equal. We would be yoked for a purpose and we would be taught and guided in our purpose by he who yoked us.
And if we are yoked then we are united to some purpose. We Christians become yoked together and so have a common and shared job to till the soil, to plant the seed, to plow the Lord's garden for His saving of souls.
Again, does this promise us an earthly life of ease and prosperity? It promises rest for our souls, not necessarily for our body. It certainly doesn't promise us prosperity. We are yoked to work for God's purpose, not our own.
I would say this, since I accepted Christ's yoke I have been care free, but not trouble free. There is a difference.
I certainly did not become moneyed. Why should I? To whom did Jesus promise a large bank account?
Wait, though, if I ask won't God give it?
So all I have to do is ask God to make me prosper and He will gift me with wealth.
You ask and do not receive, because you ask wrongly, to spend it on your passions. (James 4:3 ESV)
Let's look at "Ask, and it will be given" as it appears in Luke for some clarification.
In the TV series, "The Bible", there is a presentation of the feeding of the five thousand. A disciple lifts an empty basket over his head and says, "He said, "Ask,", then lowers the basket now full of fish and bread, and says, "And you shall receive." The scene seemed to imply that if you asked for anything you would be awarded with an overabundance of "things".
Who says God will give you an overabundance of things or wealth? I hear prosperity preaching to the effect that this promises that very thing:
Bring the full tithe into the storehouse, that there may be food in my house. And thereby put me to the test, says the Lord of hosts, if I will not open the windows of heaven for you and pour down for you a blessing until there is no more need. (Malachi 3:10 ESV)
This comes in the middle of God scolding Judah from turning aside from God and from not making full tithe as commanded. It comes in warnings of judgment. That fact does not mean that the statement is not true, that if we tithe and give that god will not open the windows of Heaven, but does this means He will make you rich? He says he will pour down blessing until there is no more need.
I have experienced this, frankly. I have given when it has been difficult. I have at times given my last dollar. Then came times when a bill was due and we had no funds to pay. Suddenly, unexpectedly, money enough to meet our debt came. It would be a source we were unaware of, sort of like a chance card in Monopoly. "Bank error in your favor. Collect $10." It was never an amount that would make us independent, only enough that there was no more immediate need. With this we should find contentment. To pursue more beyond this is dangerous.
Most times I see we Christians told to sacrifice for others without expectation of repayment, but with God's assurance that we add to our treasure in Heaven.
As for the rich in this present age, charge them not to be haughty, nor to set their hopes on the uncertainty of riches, but on God, who richly provides us with everything to enjoy. They are to do good, to be rich in good works, to be generous and ready to share, thus storing up treasure for themselves as a good foundation for the future, so that they may take hold of that which is truly life. (I Timothy 6:17-19)
God's grace is sufficient. If you are yoked by Christ, you will be okay with just enough. This is why I say, I am care free even though I am not trouble free. It is I know God will see me through what troubles may come and so I don't have to worry.
