Jude ends by exhorting us to yield the very highest esteem to God. It is a doxology of duty and obligation.
There will be those who stumble at reading the word of God, who cut devotions, or who read mechanically, not prayerfully, who do not take it in, who do not enjoy it. It is a stumble. There are people who stumble in prayer. You are not bringing things before the Lord. You do not have an adequate prayer time. You do not really praise him or you do not seek his blessing. You do not repent properly of your sin. You do not have a ministry of intercession which you keep to for other people and bring them before him. You do not always have devotions. That is a terrific stumble. And there are people who are tripped on appearances. They seem to come to the Lord, but they have spent so much time, money, and attention grooming themselves, changing hairstyles and clothing and so on, and so many hours in gyms to look better. It is a snare.
Covetousness is another serious cause of stumbling. I must have a still bigger house or a still better car. Once the devil has got you into that, it takes you further and further, so that now you have got two masters – God and mammon. And sometimes, and I say this delicately, sometimes you get a grand young couple, and they trip at the first baby. Suddenly their entire lifestyle changes. They are no longer in the house of God, no longer in Christian service. A new life has come into the world, and it is a great treasure, but it has become everything.
