'Way of the Lord' in the Bible

This man was instructed in the way of the Lord; and being fervent in the spirit, he spake and taught diligently the things of the Lord, knowing only the baptism of John.

and he began to preach boldly in the synagogue. But Priscilla and Aquila, having heard him, took him to themselves, and expounded unto him the way of the Lord more perfectly.

When divers waxed hard hearted, and believed not, but spake evil of the way of the Lord, and that before the multitude: he departed from them; And separated the disciples away; And disputed daily in the school of one called Tyrannus.
