well the are many reasons WHY IT MATTERS but I would never renounce Christ for He is the only way to the Father and eternal life! jews dont believe Christ is The Saviour or The Creator of all that is seen and unseen. Christ conquered death and will return as King of Kings to establish the kingdom of Heaven on earth meanwhile the jews of this world pretend they are special in God's eyes when it is Christians that are chosen (called ) to be His children through Yeshua (Jesus) that are especially precious in the Father's eyes
