For instance, most can pray, even if they can do nothing else. What a critical role to play in the kingdom, interceding on behalf of others!
Some can share the gospel with family members, friends, staff and other residents.
Many can at least hand out Gospel tracts to these people, and you can keep them supplied with materials from your church or a five-star source such as www.LivingWaters.com.
Some can show the difference Christ makes to their lives simply by the way they think, speak and act.
It may pay eternal dividends if you will take the time to encourage them in such activities.
