And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus. 2 Timothy 3:15.
Silas, Paul's companion in labor, was a tried worker, gifted with the spirit of prophecy; but the work to be done was so great that there was need of training more laborers for active service. In Timothy, Paul saw one who appreciated the sacredness of the work of a minister; who was not appalled at the prospect of suffering and persecution; and who was willing to be taught. Yet the apostle did not venture to take the responsibility of giving Timothy, an untried youth, a training in the gospel ministry, without first fully satisfying himself in regard to his character and his past life.
Timothy's father was a Greek and his mother a Jewess. From a child he had known the Scriptures. The piety that he saw in his home life was sound and sensible. The faith of his mother and his grandmother in the sacred oracles was to him a constant reminder of the blessing in doing God's will. The Word of God was the rule by which these two godly women had guided Timothy. The spiritual power of the lessons that he had received from them kept him pure in speech and unsullied by the evil influences with which he was surrounded. Thus his home instructors had cooperated with God in preparing him to bear burdens.
Paul saw that Timothy was faithful, steadfast, and true, and he chose him as a companion in labor and travel. Those who had taught Timothy in his childhood were rewarded by seeing the son of their care linked in close fellowship with the great apostle. Timothy was a mere youth when he was chosen by God to be a teacher, but his principles had been so established by his early education that he was fitted to take his place as Paul's helper. And though young, he bore his responsibilities with Christian meekness....
Paul loved Timothy, his “own son in the faith” (1 Timothy 1:2). The great apostle often drew the younger disciple out, questioning him in regard to Scripture history, and as they traveled from place to place, he carefully taught him how to do successful work. Both Paul and Silas ... sought to deepen the impression ... of the sacred, serious nature of the work of the gospel minister.
In his work, Timothy constantly sought Paul's advice and instruction. He did not move from impulse, but exercised consideration and calm thought, inquiring at every step, Is this the way of the Lord? The Holy Spirit found in him one who could be molded and fashioned as a temple for the indwelling of the divine Presence.
As the lessons of the Bible are wrought into the daily life, they have a deep and lasting influence upon the character. These lessons Timothy learned and practiced (The Acts of the Apostles, 203-205).
