Contrary to what is taught in some evangelical circles today, there simply is no such thing as trusting Christ as Savior without at the same moment submitting to Him as Lord. Whereas the believer was once under the lordship of Satan, through saving faith he eagerly places himself under the lordship of Jesus Christ. Whereas he was once the enemy of God and the slave of sin, he is now the loyal subject of his Lord and Master.
John MacArthur
