Jesus tells us not to deny him because He is with us and He is our helper. It’s for our benefit not to deny Jesus. If someone like Peter denies Jesus, Jesus does not destroy us but He continues to love us. When we make a mistake in life, we need to acknowledge and confess and get back to the right relationship with God—denying Jesus does not help us. Confessing Jesus in our lives will help us to have a joyful life.
