Another attempt of man trying to come to God univited is in Numbers 16.

.........................Korah and a group of leaders of Israel were upset with Moses and Aaron. They insisted that they had just a much right to go to God as any of God's appointed High Priest's did.

..................So in the presence of everyone, Moses invited Korah and the others to come before God. As soon as they came, Moses warned the other people to get away.

.............When Moses stopped speaking, the earth opened up and Korah and the others with their families dropped into Sheol alive.
