A Healthy Addiction

Is there such a thing as a 'healthy addiction'?
Yes, there is.
As it says in 1 Corinthians 16:15-16,
15¶ I beseech you, brethren, (ye know the house of Stephanas, that it is the firstfruits of Achaia, and that they have addicted themselves to the ministry of the saints,)

16 That ye submit yourselves unto such, and to every one that helpeth with us, and laboureth.

What if we each worked at developing this addiction? Not to gain anything per se as much as to be a blessing to those who served us in ministry.
Imagine that . .
