The things which you learned and received and heard and saw in me, these do, and the God of peace will be with you.
— Philippians 4:9
The Bible says, “Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things” (Philippians 4:8).
Here we find the Biblical secret of mental health. Actually, it is a secret not only of mental health but also of a happy life, of a positive attitude, of a winsome personality, of advancement in life, of acceptance by others. Certainly these are things that every one of us desires. You can be sure that losers and loners do none of these things that are revealed in this tremendous chapter of the New Testament. That is precisely why they are losers and loners. People who are ever-failures in life are such because they ignore, to their own detriment, these great teachings from the Word of God.
It takes discipline to train the mind, just as it takes discipline to train the body. But it pays us back well when we focus on positive things. In the big picture, for the Christian our thinking should be positive because the overall reality is positive. Our past is forgiven, our present is abundant life in Christ, and our future is eternal life with Jesus in heaven.
