Three things I want you to consider as you read. God will not force His way upon you. A person either agrees to submit to the will of God or reject it. Acts 16.29-34.
This is true because God made everyone of free will and with choice man is in the position to say yes or say no. Luke 7.29-30. All the Lord ever said was whosoever, let that person come. Matt 10.32-33. Rev 22.17. The conclusion is, one can do whatever they want, serve the Lord or serve the Devil. Don?t be offended, for there are only two masters, Satan or God. Matt 6.24. Matt 4.8-11. Jas 4.7-8. 1 Pt 5.8
The bible which is the word of God is available for reading. One can read its pages and see in the new testament that Jesus died to save men from sin. John 3.16. All men need to do is turn their lives over to God, so He can teach them the words of life and they can live holy and be pleasing to God. 1 Peter 1:13-25. Rom 6.16-18.
Since the bible is available for man, it will serve as the rule by which man will be judged. John 12.48. Rev 20.12. A person will stand before Jesus on the day of Judgement and that person life will be compared to what is written in scripture. If the life matches what is taught in scripture that person will go to heaven. If not, the person will go to hell.
So yes, we have the right to choose not to serve God. But remember, we all will be judged according to our works. 2 Cor 5.10. Matt 16.27
