New converts to Christianity are spoken of in the Bible as babes in Christ, with hearts full of desire for understanding, and minds equally full of problems and questions. Peter (I Peter 2:2) tells us that what they need is the sincere milk of the Word, if they are to grow to a healthy maturity. When they are grown up there is solid food for them too; but until then they need milk and not meat.
Many young Christians have suffered life-long spiritual indigestion, or the diseases that spring from malnutrition owing to a wrong diet in their early days. Those who are ignorant of the Scriptures can be misled by any teacher with strong personality, and need to acquire for themselves that full assurance of understanding of which St. Paul speaks. (Col. 2:2, Heb. 10:22.)
It is of the first importance therefore to know what is meant by the milk of the Word; and our Father has left us in no doubt on this matter, but has detailed it for us in Hebrews 5:11 to 6:2.
The Foundation Truths, the A.B.C. of Christianity, are seven in number, Repentance from dead works, Faith towards God, Baptism in Water, Baptism in Spirit, the Laying on of hands, Resurrection of the dead, Eternal Judgment. Only after he has learnt the truth in these simple matters is the Christian baby ready to consider the harder problems and deeper wisdom of God's Revelation.
These studies are designed primarily therefore to lead the new convert to those passages of the Bible in which these matters are most simply handled, that he may see for himself the Scriptural basis of his faith, and be fully persuaded in his own mind. In the hour of battle a man cannot stand upon another's teaching, but only upon those parts of the Truth that he has made his own.
It will soon become apparent to him that these Foundation Truths show the steps by which His Heavenly Father plans to change a "man born of woman," who was rightly at home on this earth, into a mature "Son of God" who longs for His Heavenly home and destiny.
