Zac Poonen emphasizes the importance of preparation for marriage, likening it to the meticulous planning required for a space mission. He advocates for a period of engagement that allows couples to know each other better and to detach from parental attachments, while also warning against the dangers of physical intimacy before marriage. Poonen highlights that minor disagreements during engagement are normal and should not be seen as signs of incompatibility, but rather as opportunities for growth and humility. He stresses the need for couples to seek advice from experienced married believers and to plan a Christ-honoring wedding, free from non-Christian customs. Ultimately, he encourages couples to establish their own home after marriage to foster a healthy family unit.
