Who Will Enter the Kingdom?

In the previous sermon (Luke 18:15-17) we saw that children are a part of God's kingdom. If children enter into the Kingdom, why is it that so many adults fail to enter in? How is it that we are made partakers of the glorious inheritance promised to God's children? How may we be certain that we are in the Kingdom? Are some people (the rich, the religious, those with good reputations) more likely to enter in than others? In this sermon we learn what Jesus said to a rich, young ruler who lacked assurance of salvation in His day.
