Be continually benevolent. Look at what Jesus said on the subject in Matt. 5:42 and Acts 20:35. The way to an unbeliever’s heart is often through his mouth. The gift of a hamburger many speak much louder of your love than a powerful sermon in a deaf ear.
Ecclesiastes 11:1 Cast your bread upon the waters, Cast your bread upon the waters, For you will find it after many days.
