Has he? Has Jesus changed just your Sundays or maybe your Wednesdays as well? What about the rest of the week? Accepting him as your Lord and Savior should change everything on every day!
Before salvation you may or may not have been aware of it, but you were destined for hell. Once you received Christ you were born again and are now destined for heaven and an eternity with him. You will still stumble and sin, but he is faithful and just to forgive you.
Your lifestyle should be transformed into one that demonstrates a committed walk with God. Your old desires must be replaced by a desire to seek purity and holiness. If you are trapped in your old sins you need to give them all to him and allow him to change you. Has Jesus changed your life?
Romans 12:2 (NKJV) - “And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.”
