The medical-doctor-turned-preacher David Martyn Lloyd-Jones divided his ministry of the word into three different groups. On Sunday mornings he would typically preach to the converted focussing on the experience of Christian faith and the practise thereof in daily godliness. On Sunday evenings his focus would typically be on the unconverted, bringing Biblical truth on sin, salvation and the need for repentance to bear upon their souls. His mid-week meeting would have a distinct doctrinal focus, elaborating on the grand truths of the Scripture, in the consecutive exposition of the Scriptures.

Christian growth, Evangelistic zeal, and Doctrinal clarity are indeed the three hallmarks of a Christian. Scripture is useful for these three areas of a Christian’s life.

Every Christian must engage in a pursuit of maturity in his/her Christian walk. Terms like faith, obedience, endurance, and worship can be associated with this first use of the Scriptures.

Every Christian must engage the lost with the Gospel of Jesus Christ. Terms like sin, repentance, confession, belief, and conversion are to be clearly explained from the Scriptures for sinners to come to salvation.

Every Christian must engage in a full understanding of the Divinely-revealed, profitable-for-all, truths of Scripture. Terms like regeneration, election, justification, sanctification, glorification, propitiation, and a host more need to be studied over the course of a believer’s life.

These three uses (maturity, evangelism, doctrine) of Scripture are something few Christians are skilled at. In the one you find yourself strong, use that strength to God’s glory. In the one you find yourself weak, strengthen yourself.

Psalm 19:7-10
The law of the LORD is perfect, reviving the soul;
the testimony of the LORD is sure, making wise the simple;
the precepts of the LORD are right, rejoicing the heart;
the commandment of the LORD is pure, enlightening the eyes;
the fear of the LORD is clean, enduring forever;
the rules of the LORD are true, and righteous altogether.
More to be desired are they than gold, even much fine gold;
sweeter also than honey and drippings of the honeycomb.
