3rd John 1:2 Beloved, I wish above all things that thou mayest prosper and be in health, even as thy soul prospers.
In order for us to understand our first passage in its entirety, it would be necessary for us to remove far our minds any preconceived ideas and personal biases or preferences for certain interpretations and allow the Bible to speak authoritatively for itself. The gospel, which is often referred to as the good news does not push anyone down, as is so often the case when persons go for healing by false prophets, because it is designed to lift up souls, and bring out the fullest potential, and the very best in us, whenever it is properly received.
Devils will have persons believe that having Christ as Lord and Savior puts folks at a disadvantage, but in reality, this is absolutely not the case, for wherever the laws of God, and the principles of His kingdom are adopted and practiced, the human agent would experience very great changes for the better, never the worse. Persons who truly receive Christ and His gospel of salvation become better persons on all fronts, for this is what the gospel is designed to accomplish in all who submit to its teachings.
True Christians are to become better at whatsoever they do; they are to become better workmen, better citizens, better in health, better stewards, and better in their social relationships. The gospel of Christ has never set a single soul on a downward trajectory in any area of life. Believers do have their struggles, and challenges like everyone else but when their lives, before and after accepting Christ are evaluated, it will always be found that the good news made persons better off, not worse.
John 10:10 The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly.
May The Lord add His blessing to the study of His word. God bless!
