God has given everyone work to do.
Some people are working backstage, some are playing in the orchestra, some are on stage singing, some are in the audience as critics and some are there to applaud.
Know where you are supposed to be and what you are supposed to do. It is just as important to know what NOT to do as it is to know what to do.
Aaron and his sons shall go in and assign each to a particular task or burden. But the Kohathites must not go in to look on the holy things even for a moment; otherwise they will die. (Numbers 5:19b-20)
In the above scripture of a seldom read passage, God clearly stated that the Kohathites were not to do the work of the Levitical priests. In fact, they were not even to look on the holy things; otherwise they would die. Even though Kohath was a descendant of Levi, it was Aaron and his sons who were given priestly duties.
So it is with us. All have been given specific tasks to do for the kingdom of God. When we neglect our duties to perform the duties assigned to others, all suffer. We are not to cross crafts because someone else's job, task, or mission looks good to us. God anoints us to do what He has called us to do. To try to do otherwise is punishable by death (no blessings, no anointing, no power).
Crossing callings are not allowed! Let's work in our own callings to please God!
