As people today become interested in Christianity often they are told to “pray to Jesus and accept him as their personal savior” or simply to come and “join the church.” Unfortunately, you will not find these phrases or anything like them in the scriptures.
You likely have heard or know of similar suggestions made by teachers and preachers either on television or in print. Let me suggest that it is useful to use biblical concepts and biblical expressions when talking about Christianity and the things that call us out to take up the name and title of Jesus and to become known as Christians.
1) They have not all obeyed the gospel. (Romans 10:16).
2) Taking vengeance… on those who do not obey the gospel of our Lord Jesus Christ. (2 Thessalonians 1:8).
3) What will be the end of those who do not obey the gospel of God? (1 Peter 4:17).
4) Who has bewitched you that you should not obey the truth…? (Galatians 3:1) and Who hindered you from obeying the truth? (5:7).
5) For this end I also wrote, that I might put you to the test, whether you are obedient in all things. (2 Corinthians 2:9).
That should do for starters.
The word obedience or obey in the Greek language is where we get our word acoustics – that which has to do with hearing. So being under obedience means to respond to what we hear. The word gospel simply means good news. It would seem then on quick inspection, that obedience is more than just accepting Jesus as our personal savior.
So then faith comes by hearing and hearing by the Word of God.
