An observant traveler in Europe will quickly notice the abundance of large, old, beautiful churches, but also realize that these churches are usually empty, or nearly so, even Sunday morning, during traditional “church time.” Much has been written about the growth of secularism, the death of Christianity or the rise of Islam in Europe. Most articles focus on Western Europe, where these particular trends are most evident, even conveniently ignoring much of Eastern and Central Europe. However, as we shall see, the existing Church, whether in more secularized Western Europe, or more traditional Eastern Europe, is frequently characterized by a “Christian in name only”, a Christmas-and-Easter, wedding-baptism-funeral form of Christian nominalism.
We will look at Jesus’ teaching from the end of the Sermon on the Mount, where He demands a radical choice, and use His words to examine nominal Christianity in Europe, and propose some strategies for evangelizing Europeans. Probably, some issues will be similar for nominal Christians in America, as well.
13 “Enter by the narrow gate. For the gate is wide and the way is easy that leads to destruction, and those who enter by it are many. 14 For the gate is narrow and the way is hard that leads to life, and those who find it are few.
15 “Beware of false prophets, who come to you in sheep’s clothing but inwardly are ravenous wolves. 16 You will recognize them by their fruits. Are grapes gathered from thornbushes, or figs from thistles? 17 So, every healthy tree bears good fruit, but the diseased tree bears bad fruit. 18 A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Thus you will recognize them by their fruits.
21 “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven. 22 On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?’ 23 And then will I declare to them, ‘I never knew you; depart from me, you workers of lawlessness.’
24 “Everyone then who hears these words of mine and does them will be like a wise man who built his house on the rock. 25 And the rain fell, and the floods came, and the winds blew and beat on that house, but it did not fall, because it had been founded on the rock. 26 And everyone who hears these words of mine and does not do them will be like a foolish man who built his house on the sand. 27 And the rain fell, and the floods came, and the winds blew and beat against that house, and it fell, and great was the fall of it.” 
At the conclusion of the Sermon on the Mount, Jesus presents a series of metaphors that illustrate the truth that there are only two choices for people in the world, no matter how much of a middle ground we would like to see. “He utilizes a “two-ways” genre well-known from other Jewish literature (e.g., Deut 30:15–20; 2 Esdr 7:1–16; cf. also Did. 1:1–6:7).” We see two ways (13-14), two fruits (15-20), two professions (21-23) and two foundations (24-27).
Warren Wiersbe suggests that Christ proposes three tests that prove our Christianity: the test of self-denial (13–14), the test of spiritual fruit (15–23), and the test of permanence or obedience (24–27). A false, counterfeit Christianity will fail these tests. Or, put in the form of three questions:
Did my profession of faith in Christ cost me anything?
Did my decision for Christ change my life?
In the end, what will God say?
