If you mix milk with honey (and freeze it), you get ice cream.
What the in the Old Testament is promised to God’s people (to possess the Land of Milk and Honey) is in the New Testament promised as “abundant life.” Jesus says: I have come that you may have life — life abundantly. (John 10:10).
The idea is that serving Jesus not asceticism. It is joy. When Jesus was born, “peace” and “great joy” was promised to Earth. Salvation would be lavished upon humanity with blessings, both here and in Heaven.
I love ice cream. It is a good symbol for the Christian life. I hope you can learn to enjoy a relationship with Jesus Christ (not empty rigorous religion with rules and hopelessness).
