Thank you for posting. If one may add some thoughts to this dialogue;
Religion is man by mans efforts seeking the approbation of God.
Christianity is a relationship with God through Jesus Christ.
A big difference.
It is faith alone in Christ alone. No religion has a monopoly on truth. The translation from the Koine Greek language...For you see, God so loved the world, the human race, that He gave His uniquely born Son, that anyone who believes in Him shall not perish but have eternal life. John 3.16 from the New Testament of the Holy Bible.
Thank you for giving it a hearing. Wishing you all the best. Cheers.
