It is clear that the nature world is controlled by more than the visible and known. There is a spiritual "influence" which has an effect on our lives, we might not know about it, but it is still there.
Ephesians 6
:10 Finally, my brethren, be strong in the Lord and in the power of His might.
:11 Put on the whole armor of God, that you may be able to stand against the wiles of the devil.
:12 For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places.
2 Corinthians 10
:3 For though we walk in the flesh, we do not war according to the flesh.
:4 For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds,
:5 casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ,
:6 and being ready to punish all disobedience when your obedience is fulfilled.
Therefor it is helpful to learn about it and get understanding from God. A great deal of these spiritual activities is the reality of angels. To learn about angels from the Word of God can help us to understand:
the greatness of God
how much God loves us by taking care of us
the holiness and righteousness of God
to have a sensitivity of the spiritual world
bring us closer to God
It is very important to know that angels are spirit beings and are not to be worship. They are not God. Only God can be worshiped.
God has made man a little lower than Himself. In Psalm 8:5 we see: "For You have made him a little lower than the angels, And You have crowned him with glory and honor." The word "angels" here is wrongly translated. From the original Scriptures it is "Elohim". That is God. Angels are also creations of God, but no where in the Word we read the same about angels - that they are "a little lower than God". The authority to rule over the works of God's hands was given to man not to angels. How then, can we worship angels? We worship God and God alone.
God created angels with a purpose. We can see God's purpose for angels in the following verses:
Psalm 103
:20 Bless the LORD, you His angels, Who excel in strength, who do His word,
Heeding the voice of His word.
:21 Bless the LORD, all you His hosts, You ministers of His, who do His pleasure.
It is a fivefold ministry of angels. These verses show God's purpose for angels. Angels exist to serve God in five ways.
to "bless the LORD" in worship and service
to "do His word" concerning activities on Earth
to "heed the voice of God's word" as it is spoken through the believers on Earth
to "minister on God's behalf" as described in Heb. 1.14
to "do God's pleasure" as His hosts are at His direction
Angels are also messengers of God.
Acts 8:26
:26 "Now an angel of the Lord spoke to Philip, saying, "Arise and go toward the south along the road which goes down from Jerusalem to Gaza." This is desert."
With God's Word as our source of information, we see that angels may be actively involved in assisting the advance of the church on earth through messages. Philip had evangelized in Jerusalem and Samaria, but it was a messenger angel who told him to go into the desert where he met the Ethiopian eunuch. Acts 10 also reveals angelic intervention on behalf of Cornelius, and the church was enlarged to include Gentiles. As with the supernatural gifts of the Spirit, angelic activity did not cease after the time of the apostles. Angels are still actively involved with building God's kingdom on earth. Nevertheless we would do well to heed Paul's warning "But even if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed" (Gal. 1.8).
Psalm 91
:11 For He shall give His angels charge over you, To keep you in all your ways.
:12 In their hands they shall bear you up, Lest you dash your foot against a stone.
Each of us has our own private guardian angels. Ps 91:4 speaks of God "covering us with His feathers" and mentions that we are under His "wings." Since God has no feathers or wings, some have suggested that these feathers and wings speak of our guardian angels' wings, which protectively cover us to keep us from falling, getting lost, or stumbling into unknown dangers in the unseen realm of the spirit.
Angels are ministering spirits.
Hebrews 1:14
:14 "Are they not all ministering spirits sent forth to minister for those who will inherit salvation?"
A careful study will reveal that the activity of angels usually revolves around the ministry of Jesus and the establishment of His church on earth. They "minister" referring to their "serviceable labor - assistance". They are ministering spirits, or heavenly assistants, who are continually active today in building the body of Christ- advancing the ministry of Jesus and the building of His church.
Angels accompanied believers.
Luke 16:22
:22 "So it was that the beggar died, and was carried by the angels to Abraham's bosom. The rich man also died and was buried."
The Bible indicates angels in the future of all believers, at death or at Jesus' Second Coming. Should death occur, at our transition between this life and the next, it will not be a lonely, dreadful experience, rather, angels will accompany us into everlasting joy just as they carried the beggar to the resting place appointed for him by God. For us, that will be Jesus' presence (2 Cor. 5:1-8). However, if Christ returns before our death, at the Second Coming the angels will gather us to Christ "from the farthest part of earth to the farthest part of heaven" (Mark 13:26, 27).
