As a christian is dating or being in a relationship without sexual intercause a sin?
First you must know what sin is. Then once you know what sin is, did Christ take it away?
1John 3:5 - and we know that He was manifested (appeared) to take away our sin and imn Him is no sin.
Did He take away our sins or not?
You must study God's word to know these things. Read: 1Corinthians 2:7-16. This will teach you the very first things you should know before going on. God bless you.
Yes he did die for our sins so which means he took away our sins..that is what i think but i will read those scriptures deeply.
Being in a relationship without sex I think is not sinful. Though much care should be taken. He who calls it sin is indirectly saying that Christian do not have to undergo courtship. You can have a friend,help each other in one way or the other. Who knows,God May be leading you to your spouse to be. Live and love.
