To be anointed means that a person is assigned or appointed a task. The fact we are anointed by God means there is a supernatural blessing or endowment that accompanies the assignment.
2 Corinthians 1:21 And it is God who establishes us with you in Christ, and has anointed us.
Hebrews 1:9 You have loved righteousness and hated wickedness; therefore God, your God, has anointed you with the oil of gladness beyond your companions.”
1 John 2:20 But you have been anointed by the Holy One, and you all have knowledge.
God anoints Jesus’ disciples only when He enables them to fulfil the assignment given. God never assigns a task that is impossible to be completed. It may be humanly impossible, but if the task is assigned, it can be fulfilled. When God calls us to something – often far bigger than we are capable of – we can always have the full confidence that He also empowers and enables the disciple to accomplish it. It requires a lot of faith at times, but what a blessing to be anointed by God!
