In the little daily devotional "Daily Bread" there is a May 15th entry on The Secret.
It says, "If you believe Rhonda Byrne, author of the bestselling book The Secret, 'The shortcut to anything you want in your life is to be and feel happy now!' According to Byrne, this has to do with something called the law of attraction. If you think only about things that make you happy, she says, happy things will be attracted to you. Sounds easy enough.
However, the bible says that 'the secret' to life is something very different. It has to do with 'the law of the spirit of life' that sets us free from 'the law of sin and death' (Rom 8:2), not with the 'law of attraction.'
According to the apostle Paul, the most important thing to know is 'Jesus Christ and Him crucified' (1 Cor. 2:2). To those who are concerned with happiness now, this is indeed foolishness (v 14). They do not recognize the power of God in what appears to them as weakness.
The Lord created us with a desire to know what is secret. In His wisdom, He kept certain things hidden in mystery for a time (v. 7). But now, through His Holy Spirit, He has made them known. And the secret He reveals has nothing to do with having happy thoughts in order to obtain happy things; it has to do with having the mind of Jesus Christ (v. 16).
To know lasting happiness, we must get to know Jesus.
1 Corinthians 2: 6-16
6 We speak wisdom, however, among them that are fullgrown: yet a wisdom not of this world, nor of the rulers of this world, who are coming to nought:
7 but we speak God's wisdom in a mystery, even the wisdom that hath been hidden, which God foreordained before the worlds unto our glory:
8 which none of the rulers of this world hath known: for had they known it, they would not have crucified the Lord of glory:
9 but as it is written, Things which eye saw not, and ear heard not, And which entered not into the heart of man, Whatsoever things God prepared for them that love him.
10 But unto us God revealed them through the Spirit: for the Spirit searcheth all things, yea, the deep things of God.
11 For who among men knoweth the things of a man, save the spirit of the man, which is in him? even so the things of God none knoweth, save the Spirit of God.
12 But we received, not the spirit of the world, but the spirit which is from God; that we might know the things that were freely given to us of God.
13 Which things also we speak, not in words which man's wisdom teacheth, but which the Spirit teacheth; combining spiritual things with spiritual words.
14 Now the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him; and he cannot know them, because they are spiritually judged.
15 But he that is spiritual judgeth all things, and he himself is judged of no man.
16 For who hath known the mind of the Lord, that he should instruct him? But we have the mind of Christ.Go here to read a Berean review of the book.
