The churches of this world generally teach that all a person has to do is to believe on Jesus Christ. Unfortunately, intellectual and even emotional beliefs on their own produce the static, idle faith that James speaks about—dead faith. However, in one who is truly called by God—an individual who has living faith—his belief galvanizes into a conviction that will produce righteous works. These works ultimately produce the "much fruit" that will glorify God the Father (John 15:8).
Just what is the faith that Jesus Christ is looking for? It is a faith far greater than we might imagine. It is faith, not just in individual truths or doctrines, but in an entire way of life—the righteous, holy way that God Himself lives. God wants us to accept and follow the whole package of Christian living that He reveals in His Word.
Granted, it is very hard to do. We live in one of the most sinful, evil, corrupt, self-centered societies of all times, and our patience and conversion are being severely tested. The world wants us to come out of the narrow way that protects us, teaches us, and prepares us for our future. It is pushing and enticing us to accept the broad way that will pull us down to failure and destruction (Matthew 7:13-14).
But the life that God has called us to is truly awesome! In John 17:3, Jesus declares the kind of life we have been chosen to live by faith: "And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent." Living this eternal life gives us the ability to know God: how He thinks, makes decisions, shows His love, feels for others, extends mercy and forgives, etc. In other words, living God's way now allows us—as much as is humanly possible—to know the mind and ways of God. It is in God and His incredible way that we must have faith.
Because our calling and potential are so tremendous, God gives us a warning to consider in II Peter 2:20-21:
For if, after they have escaped the pollutions of the world through the knowledge of the Lord and Savior Jesus Christ, they are again entangled in them and overcome, the latter end is worse for them than the beginning. For it would have been better for them not to have known the way of righteousness, than having known it, to turn from the holy commandment delivered to them.
Once we start down this road, we have committed ourselves to following it to the very end.
For this reason, Paul challenges us in II Corinthians 13:5 to examine ourselves as to whether we are in the faith. He tells us to test ourselves to prove that Christ lives in us. We will not fail the test if we draw close to Him and truly work to make the changes we need to make as individuals to take on the very nature and life of God.
Then, when the question arises, "When the Son of man comes, will He really find faith on the earth?" the answer will be a resounding, "Yes!"
