Some of us may need to overcome feelings of guilt because of past sins. If so, why not start a personal study project that focuses on Christ’s ransom sacrifice? If we study, meditate, and pray about that upbuilding subject, we may do much to relieve unnecessary guilt. We may even stop punishing ourselves for sins that Jehovah has forgiven. Consider another lesson we can learn from Paul. Some may have given up a potentially lucrative career in order to pursue Kingdom interests. If so, can we forget the things behind by refusing to look back longingly at material opportunities we might have missed? (Num. 11:4-6; Eccl. 7:10) “The things behind” might even include things that we accomplished or trials that we endured in the past. Of course, looking back on the way Jehovah has blessed and supported us over the years can draw us closer to our Father. However, we never want to become self-satisfied, imagining that our work is done.​—1 Cor. 15:58. w19.08 3 ¶5-6
