One of the featured articles in this month’s Tabletalk on Christian maturity is written by Dr. Tom Ascol. This third main article on the theme is titled “Growing in Maturity.”
In it, Ascol not only affirms from Scripture that believers must be growing into maturity as they grow older as Christians, but he also treats the means by which we are to do so. These means of the “how” of spiritual growth are not new to us, but they are important enough to be reminded of again.
I give you here his opening paragraph on this and then his section on using the Word of God as our chief means to reach maturity.
The How of Spiritual Maturity
Growth naturally follows birth in one’s spiritual life, just as it does in one’s physical life. That it is normal, however, does not mean that it is automatic. God has provided specific instruments to lead His people to spiritual maturity. The Westminster Confession of Faith summarizes this provision:
Unto this catholic visible Church Christ has given the ministry, oracles, and ordinances of God, for the gathering and perfecting of the saints, in this life, to the end of the world: and does, by His own presence and Spirit, according to His promise, make them effectual thereunto. (WCF 25.3)
Ordinary means of grace have been provided by God for both the “gathering” (conversion) and “perfecting” (maturing) of His people. The means that God has provided for creating faith in His people are the same means by which He intends for them to grow in faith. When Scripture encourages believers to advance in the Christian life, it never has in mind that we can outgrow our need of these ordinary means. Rather, as we continue to employ these means faithfully, we are empowered to grow deeper and stronger in our relationship with Christ.
Jesus prayed to the Father, “Sanctify them in the truth; your word is truth” (John 17:17). Scripture is God’s Word written, and apart from it we cannot have a saving knowledge of God or grow in our relationship with Him. The Apostle Paul says God gave us the Scriptures to profit us through teaching, reproving, correcting, and training in righteousness so “that the man of God may be complete, equipped for every good work” (2 Tim. 3:16–17). To grow in maturity, a Christian must grow in his understanding of and submission to Scripture.
A casual acquaintance with the Bible will not suffice, as Jesus makes clear in the conclusion of His Sermon on the Mount when He contrasts a house built on a rock that withstands the storms with one built on sand that is destroyed by them. The latter represents the person who merely hears the Word of Christ without submissively complying with it. His life lacks stability. The former is like the wise man who not only hears the teachings of Jesus but “does them.” His life will be characterized by a maturity that stands firm through the trials of life.
God has designed His Word to shape us through reading and hearing (Rom. 10:17; Rev. 1:3), through meditation and memorization (Josh. 1:8; Pss. 1:1–3; 119:11), and especially through faithful preaching (2 Tim. 4:1–5).
