Religion and Relationship with God are synonymous. I am a Christian. It is my religion. How I follow Christ is my relationship with him, which is my religion.
When someone says we aren’t religious or we don’t believe in religion, we believe in relationship – often what they are really saying is we don’t believe in God’s rules. For them religion is synonymous with keeping the law and they want no part of God’s rules and regulations.
The truth is we must strive to keep the law if we want to make it to Heaven. Keeping the law is a critical part of our relationship with Jesus. Jesus said, if you love me keep my commandments. John 14:15.
He repeated it again in John 14:21 KJV: He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.
