Casual Christians are only fooling themselves. Jesus Christ said that:”Whoever wishes to come after Me must deny himself, pick up his cross daily and come here follow Me.” Jesus Christ is not interested in casual followers.
People who are lukewarm will not enter the kingdom of heaven. Jesus said that if we are lukewarm He will VOMIT us out of His mouth. If we want eternal life we must take Jesus Christ seriously and take our relationship with Him seriously.
If you are not willing to commit to utterly obey Jesus Christ and follow Him every step of the way, to deny yourself, pick up your cross and follow Him every day then you are wasting your time because you will NOT have eternal life and you will NOT enter the kingdom of heaven.
Jesus Christ requires TOTAL COMMITMENT, TOTAL OBEDIENCE UNTIL THE VERY, VERY END.
May Jesus bless you.
