Some people never change their mind about what they have determined to do even if they meet with some loss, while some others cooperate with their partners when they expect some gains but turn their back from the partners in the face of harms or loss. If anyone changes his mind according to whether or not to gain benefits, he cannot be trusted, so that he cannot gain a truthful friend nor can he receive blessing from God. I hope you get rid of slyness and shrewdness within you and accomplish truthfulness in your heart so that you can be trusted and favored by God and the people around you and live a blessed life. ¡°Let us draw near with a sincere heart in full assurance of faith, having our hearts sprinkled clean from an evil conscience and our bodies washed with pure water¡± (Hebrews 10:22).
