An ally is a personality or body that comes to the aid of another with higher ability in one area or the other, helping it to overcome, defeat or escape the oppression of an attacker or dominant circumstances.
One usually need an ally when there is signs that he or she may not be able to handle a situation alone.
For instance, when a nation find out that it cannot overcome another nation in battle, such a nation may form an alliance with other nations which are also in hostile with the nation confronting it in battle.
An example of this is association of Moab, Ammon and Mount Seir which rose up against the Israelite (2 Chronicles 20).
Despite of this alliance, the three nations were defeated by the children of Israel because they have the prominent Ally fighting on their behalf.
When Paul and Barnabas took the good new to Paphos, they were also confronted by Elymas the warlock. But if not for the prominent Ally, this warlock would have frustrated the effort to win an important personality to Christ.
With His help, Paul decleared judgment upon the spirit of sorcery at war with them and the result speaks for itself.
One major lesson to learn from this story is that witnessing for Christ without the backing of the Holy Spirit may not be successful.
The Lord Himself confirms the the Holy Spirit is the best Ally of the church in the assignment of enforcing and expanding the kingdom of God. I call Him my Senior associate and indeed He is more than that in the real sense of it.
Make sure that you also have the Holy Spirit as your Ally. However, this is only possible if Jesus Christ is not only your redeemer but also your Lord.
Romans 8:31 declared that if we have God as our Ally, victory is guaranteed, not minding how hopeless the situation at hand may seem.
Prophet Elisha woke up one morning and find out that they were surrounded by enemy soldiers with horses and chariots. Nevertheless, the prophet calmed his scared servant down.
Indeed, one with God is frankly a MAJORITY!
