For those serving the Lord in mission work, you sometimes hear them speak of “living by faith.” This usually has an economic meaning. The Scriptural principle behind it is that if you’re “seeking first the Kingdom of God” as Jesus said, then “all these things shall be added unto you.” (Matthew 6:33) Another well known verse that’s claimed by those who live by faith is what Paul said, “But my God shall supply all your needs according to His riches in glory by Christ Jesus.” (Philippians 4:19)

As you might figure, it can be a controversial doctrine. Some would say, “But what if everyone did that?!” Others will quote Paul who said, “Those who shall not work shall not eat.” (II Thessalonians 3:10) And it should go without saying that “living by faith” and serving God, seeking first the Kingdom of God, in no way implies any lack of work. It’s just that it’s work like you see in the four Gospels and the book of Acts. Folks who take this direction have verses that become much more alive to them than when they didn’t live by faith before.

Jesus said in the Sermon on the Mount, “No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one and despise the other. You cannot serve God and mammon.” (Matthew 6:24) Those living by faith and serving the Lord feel they’ve come to a full-time service for the Lord which has delivered them from daily serving mammon and the systems of this world.

Is all this mandatory? Will a person go to hell if they’re not living by faith, fully serving the Lord? No. But a deeper look at the New Testament does pretty clearly show that this was the nature of the lives of the early apostles and disciples of Jesus. Let’s face it; so much of our lives is described in what Jesus said,

“Therefore I say unto you, take no thought for your life, what you shall eat; neither for the body, what you shall put on. The life is more than meat, and the body is more than raiment…  …If then God so clothes the grass, which is to day in the field, and tomorrow is cast into the oven, how much more will he clothe you, O you of little faith? And seek not you what you shall eat, or what you shall drink, neither be of a doubtful mind. For all these things do the nations of the world seek after and your Father knows that you have need of these things.” (Luke 12:22-30)

Such famous, familiar words from the Lord. But how much they’ve been glossed over and set aside by so many believers as having no real message, meaning or promise to us practically in the real world of this day.

But when you’re “living by faith” on the mission field and all you have is the Lord (since you’ve gone into all the world and win souls), you very much see the promises and provision of God utterly come through for you, even in some of the strangest and most trying times. I wrote about one experience like that which my former wife and I had in Sweden when we first got married . You can read about that in “Foolhardy Faith”, an amazing time of miraculous provision, here.

“Well, Mark, that’s great but it’s not for me. And not for most of us, as you surely know. I need to have a normal job and a normal life like the rest of society. I’m a Christian, I go to church. But all this fanatical missionary stuff is just too far out.”

What I’ve found is that God has ways of sifting His people. He’s not trying to be mean to us. It’s just that we have more safety, security and even provision as well as meaning and happiness in serving Him, even full time, than we do in having a worldly job six days a week and then going to church on Sunday. Admitted, this is the way virtually all Christians live in these times.

Another simple thing Jesus said about this which is so often overlooked is “Lay not up for yourselves treasures on earth, where moth and rust do corrupt and thieves break through and steal. But lay up for yourselves treasures in heaven where neither moth or rust corrupt or thieves break through and steal. For where your treasure is, there will your heart be also.” (Matthew 6:19-20) Heard all that before? Certainly. But how many understand it or take it to heart and try to put it into practice.

To end with, here’s some good news. In the final days before the Lord’s return, we’re not really going to be able to serve Mammon the way most Christians do now. The Bible says that “no man will be able to buy or sell” (Revelation 13:17) unless they have the mark of the Beast of the final Anti-Christ government. The sifting will be pretty strong then.

Christians, if they want to remain Christians, will have to trust God then and probably even be serving the Lord much more than they do now. And their economics? God’s got that covered then, just as He already does now. Revelation 12:6 & 14 speaks of the believers of those times, “The woman [the believing body of Christ on earth, the bride of Christ] fled into the wilderness, where she has a place prepared of God, that they should feed her there [3 ½ years] from the face of the serpent.” In the end, before the Lord’s return, there’ll be a sifted, separated, fruit-bearing body of believers throughout the earth, living by faith and trusting Him to supply all their needs.
