Mark 9:43 If your hand causes you to stumble, cut it off. It is better for you to enter life maimed than with two hands to go into hell, where the fire never goes out.
There are many things in our lives we cling on to just because we think they are worth it or may be useful somewhere down the line.
What Jesus was telling us here is that it is not useful if it is not helping us to get to heaven. What use is anything if it is going to keep us out of heaven?
God wants us in heaven no matter what we have in life! Don’t hold on to things preventing you from communing with God!
