The reason it's so wrong is, first of all, it's not at all what the Bible teaches us to do in response to sorrows and trials and difficulties. If the Bible teaches us not to do something, then no matter whether we understand why it's wrong, we'd just better not do it! But it's not too hard to understand why such a habit of looking within for the answers is wrong, and even harmful. The reason why this habit is wrong is that we don't have the answers within! The Answer is outside ourselves; the answer is Christ and his word. The Bible teaches this over and over.
The reason we think it's right to look within for answers and to neglect looking outwardly to Christ and his word for answers, is that we've sort of been taught to do one and to neglect to do the other. Teaching in the church and teaching from popular books have gone downhill in these past decades. They've reflected the drift of the culture rather than the teaching of the Bible.
But the teaching of the Bible on this is a lot better news than the cultural teaching! The Bible's teaching is that it's healthy and right to look away from ourselves and to the One the Bible describes as our Example (John 13:15, 1 Peter 2:21), as the Founder and Perfecter of our faith (Hebrews 12:2), as the great High Priest who has "passed through the heavens" for us (Hebrews 4:14), as the Shepherd and Overseer of our souls (1 Peter 2:25), and on and on. We are to look to him and depend on his words and not on our wishy-washy inner selves. (If you haven't figured out how wishy-washy and undependable your inner self is yet, just give it some time.) It's really the best news that the answers are outside our foggy old thoughts and distorted old motives.
Now I've known of these things for some time and "preached" them to myself and others for some time, but still I find myself practicing this bad habit of looking inwardly for the answers. Crazy, isn't it? Yes, well it's humbling. It's enlightening to see how very entrenched this habit can be, how very difficult to forsake, how very tempting to practice. In the still, lonely hours of the night I find myself tossing and turning just like always, turning things over in my mind, trying to figure things out, wrestling with and being conquered by the "devils" within. I don't mean I have devils in me. But I do believe it's "devilish" to practice the Christian life in this way. Yet, whether because of ignorance or a willful insistence on "figuring things out" our own way, it is what we do.
This is the biblical, and better practice: looking to Christ. From Abraham, who "went out, not knowing where he was going" (Hebrews 11:8), to the Israelites who looked to the bronze serpent in the wilderness and were healed (Numbers 21:9), to the coming of the Son of Man for this purpose (John 3:14, John 12:32), God has always meant for his people to look outside themselves and to Him for their salvation, both temporal and eternal.
Christ finished the work his Father sent him to do, meaning he accomplished everything necessary for our salvation and for our being made holy and fit for heaven. He then sat down at the right hand of God, there to reign until he has "put all his enemies under his feet" (1 Corinthians 15:25). God, the Bible says, crowned Jesus with glory and honor, putting everything in subjection to him, leaving nothing out of his control. But here's our difficulty: we don't yet see everything in subjection to him. We don't yet see everything under his control. But we do see what we need to see to be ok -- "we see Him... namely Jesus" (Hebrews 2:7-9).
Someday the "not yet" will be here. Faith will become sight. There will be no more temptations to toss and turn in the night watches, looking within for answers we don't have, worrying and fretting over these present afflictions and difficulties. Until then, we--and I'll bring it back to me, to "I"-- I need to look to Jesus. He's my hero, the trailblazer, the one who has gone before, conquered and overcome, set me an example to follow, promised me the power to overcome sin and temptation with faith and obedience. No answers lie within. The only answers and the only way are outside myself, in this Hero and in his living word (Hebrews 4:12), his Spirit in us giving us the power to trust and obey.
For it was not to angels that God subjected the world to come, of which we are speaking. It has been testified somewhere,“What is man, that you are mindful of him,
or the son of man, that you care for him?
You made him for a little while lower than the angels;
you have crowned him with glory and honor,
putting everything in subjection under his feet.”Now in putting everything in subjection to him, he left nothing outside his control. At present, we do not yet see everything in subjection to him. But we see him who for a little while was made lower than the angels, namely Jesus, crowned with glory and honor because of the suffering of death, so that by the grace of God he might taste death for everyone.For it was fitting that he, for whom and by whom all things exist, in bringing many sons to glory, should make the founder of their salvation perfect through suffering. For he who sanctifies and those who are sanctified all have one source. That is why he is not ashamed to call them brothers, saying,
“I will tell of your name to my brothers, in the midst of the congregation I will sing your praise" (Hebrews 2:5-12).
