I have stressed in the past how a believer needs to grow in several respects. Let me reiterate them once again. First, after one is saved he should seek for proper knowledge of the Bible. Second, he should desire to make progress in the spiritual life, such as victory, holiness, perfect love, and so forth. This is very very important. Third, we should be fervent in winning souls. Fourth, we should trust in God with such singleness of faith that we may see God working miracles. 

There are many defects in the church today. Many believers are interested in nothing more than the expounding of Scriptures. Their knowledge is excellent, yet they neither care for nor seek after growth in spiritual life. Or some may go a step further and search for the higher life and the deeper things of God, but they neglect the other three aspects. Still others have zeal but have no knowledge. All such lopsided strivings are unhealthy. Is it not surprising that in the church today those who seek to either literally or spiritually expound the Bible, or to pursue after deeper and richer life, or to be zealous in soul winning are not lacking in number, but few there be who trust in God with a living faith so as to obtain something from Him?

Every believer should strive to develop equally these four aspects of growth so that there be no unbalanced situation.
