3. God explains the purpose for which he calls somebody.
In the case of Abraham and Moses, God spoke very clearly and told them what they had to do and what they should be. At this moment, not the “how”, but God’s claim to power in the life of a person is sorted out. God first asks for our willingness to be obedient before He confronts us with the details, the difficulties and the blessings of his calling.
The western mentality always first asks for the details in order to understand the full dimension and then to decide whether or not to obey God. But if Jesus is Lord, this is a completely different approach. Here, first the character is being formed and the obedience is being tested before somebody will be sent out.
4. God makes the place of destination and the activity clear.
With his call, He also gives details about field and areas of work. It is very possible that people are called to do things that exceed their human abilities and do not meet their expectations. In this case, they will have to trust God’s work, His presence and the Holy Spirit. After this, He will give joy with people and ministry: You will be joyful because He engages in the world and in situations.
5. God determines the time when the ministry starts and how long it will be carried out.
God’s time plan is often different from our human plans. The mission history and the lives of missionary candidates reveal sufficient examples of how impatience brings wrong results. The eagerness of Moses to take up his calling without waiting for the divine command lead to a delay of God’s plan in his life. Because Abraham and Sarah were unwilling to wait for God’s promises, Ismael was conceived.
We see Jesus not as a man who was in a hurry, but as someone who always did, at the right moment, what God expected from Him (see Gal. 4:4).
