Don't Judge Your Spiritual Condition By Feelings
The apostle Paul assured the Thessalonians that they'd learned how to walk pleasing before the Lord. He told them, "Ye have received of us how ye ought to walk and to please God" (1 Thessalonians 4:1). Paul then added this exhortation: "So ye would abound more and more" (4:1).
To abound means to increase. Paul was saying, "You've been sitting under sound gospel preaching. So now you have a solid foundation beneath you. Therefore, you ought to be increasing in grace in all ways -- in your faith, your knowledge, your love."
