Pastor walks his children through Children's Catechism question 38—especially explaining how you must be holy either to enter heaven, or to be happy there. Q38. Can anyone go to heaven with this sinful nature? No; our hearts must be changed before we can be fit for heaven. The lesson emphasizes that no one can enter heaven with an unregenerate, sinful nature, as holiness is essential for communion with God. Drawing from Hebrews 12:14 and Jesus's prayer in John 17, it distinguishes between positional holiness—being set apart to God through union with Christ—and the ongoing, transformative holiness that sanctifies believers by God's truth. This moral and spiritual renewal is not optional but necessary, for heaven is a realm of perfect purity where sin cannot coexist; without it, the glory of God would be torment rather than blessing.
