Psalms 94:11

The LORD knoweth the thoughts of man, that they are vanity.

The Lord knows the thoughts of man. He understands the principles, motives, and purposes that drive each mind. He sees people's ways, choices, and human plans, including a persistent, rebellious course. He observes both evil and good everywhere.

He knows how easily He can melt people. His Spirit like a fire can subdue the flinty heart, fill the soul with love and tenderness, and give the graces of the Holy Spirit to fit believers to go in and out in laboring for souls. Those carrying to others a knowledge of present truth are to first consecrate themselves fully to Him whose name they exalt and by living faith to pray earnestly for those they expect to visit, bringing them one by one into the presence of God, trusting His knowledge and melting power to prepare hearts.
