For they being ignorant of God’s righteousness, and seeking to establish their own righteousness, have not submitted to God. For Christ is the end of the law for righteousness to everyone who believes. Romans 10:3,4

“For with the heart one believes unto righteousness, and with the mouth, confession is made unto salvation. For the Scripture says, whoever believes in Him will not be put to shame, and whoever calls upon the name of the Lord, will be saved.”
