"his profiting might appear unto all. The same counsel is greatly needed by young men of the present age. Thoughtful consideration is essential. If men would only think more, and act less impulsively, they would meet with much greater success in their labors. We are handling subjects of infinite importance, and we cannot afford to weave into our work our own defects of character. We want to represent the character of Christ. 5T 593.2"
"Meditate upon these things; give thyself wholly to them; that thy profiting may appear to all."
The EGW passage directly quotes and applies the principle from 1 Timothy 4:15 about making one's profiting appear to all. The context of thoughtful consideration and representing Christ's character reinforces the connection.
