God: set the guidelines for our freedom…
John 8:31-32 (KJV) “Then said Jesus to those Jews which believed on him, If ye continue in my word, then are ye my disciples indeed; And ye shall know the truth, and the truth shall make you free”.
Not everyone who are Christians believe in the Lord Jesus Christ; some entertain periods of doubt about who He is and what His mission was and is to us as believers.
But the basis of our faith is knowing that Jesus is the Son of God and that He came to the earth, born of a virgin and was crucified on the cross of Calvary, was buried and rose on the third day.
Believe all of that and it shall set your mind free.
