You do not lose anything by doing good. On the other hand, you gain everything.
True believers come to understand that we as humans have many plans but what prevails is the purpose of the Lord ( Rd Prov 19:21). Many times we wonder why we haven`t yet received answers to our prayers. Some times certain peoples` relationship with God is negatively affected by prevailing circumstances; where by their love for God is conditional, depending on their acquisition of material things. Our life on earth is so limited that if you are really a believer, you cannot trade eternal happiness with momentary enjoyment. The Bible urges us to set our minds on things above rather than earthly things (Colossians 3:2). With this knowledge you will not be affected by the negative attributes of comparing oneself to others such as jealousy, covetousness and so on.
