Final answer:
Timothy was encouraged to always be prepared to preach because his calling, similar to that of the early Christian and Puritan leaders, demanded constant readiness to fulfill spiritual duties and spread the Gospel.
Step-by-step explanation:
Timothy was instructed to preach the word and be prepared at all times because of the nature of his calling, which reflected the early Christian commitment to spread the Gospel and minister to others in and out of season. This expectation is rooted in various religious and historical contexts where leaders, such as the apostle Paul and the Puritan leadership, emphasized dedication to one's calling for the greater good and the salvation of mankind. The exhortation to Timothy can be seen as aligning with this tradition of vigilance and persistent readiness to fulfill one's spiritual duties, promoting faith, providing guidance, and being prepared to counter any opposing beliefs or challenges that may arise, as exemplified in various scriptures.
