Apostle Joshua Selman teaches that divine calling is accompanied by divine backing, and when God sends and commissions a person, He commits His integrity to their success. 

Divine sending brings divine backing: When God calls and commissions someone, he also equips them and provides his backing and sustenance. This backing includes raising helpers, commanding resources, and orchestrating events to validate His purpose.

The assurance of divine provision: The sermon references John 17:18, where Jesus commissions his disciples just as God commissioned him, reassuring believers that they are not sent on their own. God's backing makes extraordinary achievements possible for ordinary people.

Proof of divine calling: The true evidence that God has sent a person is not just in their words but in the tangible proof of God's power working through them and in the reflection of Christ's character. Selman emphasizes that believers must let the evidence of being "sent by God" show in their lives.

Receiving divine strategy: Every person with a divine assignment must spend time in the "secret place" to receive God's specific blueprint for their task. The divine mandate is what God has said, but the strategy is what makes it work.
The role of Christ's character: The sermon teaches that spiritual maturity is especially seen in the manifestation of Christ's character. Selman prays against fleshly elements like anger, jealousy, and bitterness that can misrepresent and betray a person's calling.

The importance of belief in others: Selman spoke about the gratitude owed to those who believed in him early in his ministry, even when there was no obvious evidence of success. He taught that believers should not take for granted those who genuinely believe in their God-given vision.
