You cannot separate having Jesus as your Savior and living your life in obedience to Him. Christ cannot be your Savior if He is not your Lord. Yet there is very prevalent teaching out there insisting the only thing required of you is to pray a simple prayer and Jesus will then be your Savior. Not only is this a dangerous teaching, it is altogether unbiblical.
The Bible says we must first make Him our Lord, and then we will be saved (Romans 10:9). It doesn’t say we can be saved and then perhaps make Him Lord of our life. Acknowledging His Lordship comes first and must be present if we are to experience His incredible gift of salvation.
