How can you discern if someone is God- loving. A fellow Christian who loves God will always be there for you. Sometimes right by your side, sometimes through prayer, sometimes with a friendly note, carefully written, showing support in troubled times or sometimes with a simple phone call. A Loving Christian will love you no matter what. In rainy days and sunny days. Maybe they stayed up all night with you and helped you write a paper or cram for a final. Maybe they listened and empathized with you through your time of trouble.
Praying with and for each other is also demonstrative of love. Giving you gentle and Godly advice. Pointing out kindly when you are wrong.
These are the kinds of loving members of the Christian family that the Apostle Paul talks about in 1 Corinthians 13

What do we need to improve?
In what areas are we doing well?
If you want to have Godly, healthy relationships with your church family reflect and memorize 1Corinthians 13.

A friend loves at all times,
And a brother is born for adversity.
Proverbs 17:17

As in water, face reflects face,
so a man's heart reveals the man.
Proverbs 27:19
