The most basic duty and greatest need for each believer is to consciously place our whole person under the Lordship of Jesus each day, including both the belief in our heart as well as the confession with our mouth.
Because Jesus is the end of the Law, He is the source of righteousness for all who believe in Him. God calls all men and women to confess with their mouth and believe in their heart that Jesus is Lord and Savior.
Religious people often stumble over Jesus and miss God’s salvation because they depend upon good deeds and religious rituals to satisfy God’s demand for righteousness. But God’s demand for righteousness is satisfied only through faith in Jesus who offers it to us as a free gift.
If we come to God through our own efforts to be righteous, we will stumble over Jesus Christ and be ruined forever. If we come to God through faith, we will have Jesus Christ as our cornerstone and receive righteousness and life in Him.
