Do not seek technique from man at the expense of trust in God.
I'll give a simple example I've seen in my own heart, in the area of dating and finding a mate. Our society (including the Christian subculture) is in a desperate search for the right techniques for how we should do it. We have hundreds of books, blogs, and coaches who will tell us what we need to do to do dating right - just follow these simple steps, and then you will attract the right person, keep them, and have a special relationship. But I've seen in my own heart - it is easy for this focus on technique to be in direct competition with a focus on trust - trust in God's sovereign provision of the most important human relationship in our life, and trust in His providence over the entire dating/courtship process.
