It is being there to help those in need and to share Christ with those who have not made Him their Lord and Savior. But still, faithfulness is more. Faithfulness is loving Christ. Loving Christ is keeping His commandments. It always amazes me how someone who claims Christ as the Lord of their life can be so cold and matter of fact in dealing with others.
Some people have a way of being brutally truthful and thinking that it is a virtue.
I had someone tell me that one day. Being gentle in our words to others is very important if we are to let the Spirit bear fruit in our lives. Cutting words, no matter how truthful, is not of God. Gentleness is caring about others' feelings. But don't be cold, hard, and brutal either.
