This is the heart of the problem.
Psychology is at its root is anti-Christ, anti-Bible, anti-God, anti-sin, pro-Self, pro-humanistic secularism. The two cannot be integrated. Ever.
Read this helpful article on why this is so.
I also discuss more in detail about the problem with psychology here.
"Rebekah Lyons, a blogger and wife of the popular pastor Gabe Lyons, wrote this week that “anxiety and panic are my nemesis” and urged Christians not to link mental illness with spiritual weakness." ~ Washington Post
The problem with that is two fold: first Lyons is starting from personal experience rather than biblical doctrinal truth, and secondly, she's bought into the fallacy of calling something having to do with thoughts and the heart, as an "illness". If its presented as an illness, one can go to a doctor for a cure and that means medicine will end the sickness. However that's wrong thinking. There is no such thing as a "mental" illness; thoughts don't get sick, they aren't ill. A brain, a literal heart, a kidney can become ill, diseased, and those can be determined by objective, qualitative medical tests. Not so with "mental illness". Psychologists are merely trained to subjectively interpret symptoms and put them into a category in the Diagnostic Manual of mental disorders and see which ones best fit their client. Its all subjective, and the category picked will vary from psychologist to psychologist, also depending on their theory of psychology (there are over 400 types to choose from).
Lyon is incorrect when trying to urge Christians to not link "mental illness" with spiritual weakness.
Here's what the Bible says about these things:
Psa 56:3 When I am afraid, I put my trust in you.
Psa 56:4 In God, whose word I praise, in God I trust; I shall not be afraid. What can flesh do to me?
Mat 13:22 "And the one on whom seed was sown among the thorns, this is the man who hears the word, and the worry of the world and the deceitfulness of wealth choke the word, and it becomes unfruitful.
Scripture is fully and solely sufficient to deal with our hearts and minds. It really is living and active. It really does sanctify us (make us Christ-like). It really does make us competent and equipped for HIS work and His glory by His power.
2Ti 3:16 All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, 17 that the man of God may be competent, equipped for every good work.
Heb 4:12 For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart.13 And no creature is hidden from His sight, but all are naked and exposed to the eyes of Him to whom we must give account.
Psa 119:24 Your testimonies are my delight; they are my counselors.
Elsewhere I have dealt with this issue: here and here.
John MacArthur rightly states in relation to Colossians 2 dealing with philosophies:"Philosophy is empty deceit. It is an empty lie. It is a delusion because it sounds good, it attracts the mind, it seduces the mind, it has certain properties of rationality, but it has no spiritual value at all. Why? Because verse 8 says it is according to the tradition of men. It’s human. If you want to know divine truth, if you want to know supernatural truth, don’t go to a human source. It’s that simple. Because all you’re going to get out of a human source is human wisdom. And human wisdom does not transcend time and space. It is just inadequate human thinking and, 1 Corinthians 2:14 says, the natural man understands not the things of God. How can he know them? They’re spiritual. They’re not in his dimensions."
