Perhaps as an incentive we could offer a free gift? There are some lovely vintage-style inkwells available together with more modern designs so a choice is available. Now that so many choose physicians over Christ it's more important than ever to get God back into the learning environment. Here's a small selection, together with a word of caution.
A WORD OF CAUTION
Leaven within the learner group holds that “ink” is not a
writing material but a demonic imprint upon one's body.
It's essential when introducing ink to make clear that does NOT mean turning up with “ink” on the arm, or on the head, or on the indeterminate body part because whether of a jolly demon or a butterfly or a menacing devil the mind behind it all is the same mind. Satan's mind. Even for half-indoctrinated social democrats who think (or have been taught) that demons & devils are shorthand terms for complicated brain states or malfunctioning glands, patience is advised: just explain “ink” is the final stage of brain disorder or glandular dysfunction and when they ask
why, then you can share The Gospel with them and explain how sin arose requiring Christ to be murdered so horribly using examples from Scripture, the best history lesson of all.
