If you have a gifted evangelist in your church, ask them to explain why and how they share the Gospel with others.
If there is a new Christian in your church, ask how they are going and how you might help meet any needs they have.
In your small group, discuss the different ways people might experience God during the worship service.
Next time you hear a biblical principle in the sermon which you can readily take and apply in your life, let the preacher know what principle you learnt and how you intend to apply it.
Next time you experience something from God during the worship service tell someone immediately after the service in a very matter-of-fact way.
Ask anyone you come across in your church, who seems to have some longer-term tension with another person, to tell you one or more positive things about that person, then encourage them to communicate those to the other person in some way.
Make eye contact and shake hands or greet someone from your church with whom you have had even the slightest relational tension and ask how they are going generally or with one of their specific areas of interest.
Share with someone why you believe they have a particular gift that is better developed in them than in yourself.
Allow more time than usual in an upcoming personal or group meeting when you will visibly put aside the agenda, your diary, your phone and all other distractions and purely focus your interest and attention on the person with whom you are meeting, as a person.
