Angels: Their Duties and Function within Christianity
Angels and apostles have always been God's messengers in the bible. Angels are ministering spirits enlisted in God's heavenly army with the main task of assisting those who will inherit salvation (Heb.1.14).
These messengers assist believers. At times they are also tasked with special message delivery to non-believers as in the case of the Roman soldiers who guarded Jesus' tomb. It was an angel who delivered the Good News about God-incarnate to a young woman named Mary. It was an angel who warned Joseph, Jesus' stepfather, to escape to Egypt. Angels are still tasked with this ministry even today.They still appear in real life or in dreams.
Ordinarily we cannot see angels because they are spirits. But as God permits, there are times when they become visible. Today, they continue to appear bodily as "strangers," and thus the bible warns us to be kind to all people, even strangers (Heb.13.1). There are countless situations in Scriptures where mortals saw angels.
They Fight Evil Spirits for Us
Spiritual war and battles always rage around us often unseen by the naked eyes. We may not see it but devils get bashed in the head or thrown off far away or zapped with spiritual electricity from a sword by mighty warrior angels as we pray unceasingly or maintain faith in the face of extreme difficulties.
In Daniel 9 and 10, we see this battle happening. It was not expressed in detail but we're given the impression that an angel was faced with fierce resistance causing a delay in the delivery of a message for Daniel. We see angels in the Old Testament sometimes with drawn swords. This means they use supernatural swords and other weapons to fight devils with.
Angels win battles for us depending on how steadfast we are in faith. If we falter in faith, they have no choice but to retreat, not out of defeat but because God will command them so, and the power of darkness will hover around us. It would be difficult for angels to rescue us then, unless we repent and strengthen in faith. When we worship in Spirit and truth, angels are given a go signal from God to attack relentlessly. And there demons' heads will roll. If we maintain faith no matter what, angels win for us and drive out darkness. Was the delay in delivering the message to Daniel because of Daniel's weak faith? Some delays are within God's permissive will, not due to weakness of faith. And God's delays never result to help being sent too late.
A Powerful Wall of Fire
Angels surround God's servants who are cornered by the enemy. We find this in the case of Elisha and his servant. As the enemy surrounded them, they were backed up by angels in fiery chariots who counted more than the adversaries. This is an automatic provision from God. When you're in danger, this wall of fire is automatically set off. But if you're a Christian non-believer, sorry.
Christian non-believers are different from those who have weak faith. The weak faith gets extra of God's grace. The Christian non-believers (mockers) get nothing.
Angels Give Directions
The Holy Spirit guides us, no doubt. But many times, he does this by sending messengers, as in the case of Peter in Acts 12 when an angel told him what he should do after being miraculously freed from prison. Yes, angels also help believers escape traps and prisons. Daniel was kept from being devoured by lions due to a mighty warrior angel who stopped the lions' mouths.
Angels can Kill Humans
In Hezekiah's time a powerful warrior angel killed 185,000 Assyrians in one stroke (2 Kings19). David was afraid when he saw a warrior angel with outstretched hand over Israel at the threshing floor of Araunah (2 Sam.24). That time 70,000 had already died. Even unarmed, warrior angels can inflict terrible damage with their bare hands.
Angels are also powerful worshipers. Like the living creatures in Ezekiel and the book of Revelations. Lucifer was once a model worshiper before he sinned. At times angels help us worship or joins us in worship when God is pleased with our faith. Remember, the key to angelic activity in your life is radical faith in God.
The ministries of angels better work when we know and believe how they minister to us. The problem is, most church people are ignorant about this and even refuse to believe that angels still exist in our midst, visible and invisible. Without faith, we cannot please God--and angels will not move a "muscle" if their Master is not pleased--except probably to destroy unbelievers.
