Any time your conscience is outraged and you don’t settle things, you are weakened, hindered, and deterred from doing that which is effective in the Will of God.
Thoughtless and selfish words and actions may indeed be something that you think you’re getting away with. Of course that’s doubtful. You never get away with anything do you, in this life?
Establish new believers by keeping in contact, listening actively, addressing their needs with God’s Word, help them develop an action plan based on their need by using God’s Word.
