K.P. Yohannan emphasizes the distinction between authentic and synthetic Christianity, using the metaphor of a vibrant synthetic plant to illustrate how many Christian activities may appear genuine but lack true spiritual life. He warns that zeal and good works can be motivated by a desire for personal gain or recognition rather than a pure heart for God. The church at Ephesus serves as a cautionary example, having lost their first love despite their hard work and dedication. Yohannan urges believers to examine their motivations and seek God's approval rather than the praise of men, reminding them that only authentic faith can produce lasting fruit. He concludes by stressing the importance of inner purity and sincerity in all acts of service to God.
