It is clear from the Scriptures that angels exist. They are actually mentioned in 37 of the books of the Bible. Jesus Himself speaks of them (Mt 25:31-32, 41) and interacts with them (Mt 4:11). Here are some of the basic teachings about angels from the Scriptures:
1. They are spirit beings. They are called “spirits” (Heb 1:14) and do not have bodies. They also do not die (Lk 20:36) or get married (Mk 12:25). However, they do appear in human form sometimes (Gen 18:3).
2. They are created beings. Ps 148:2-5; Job 38: 6-7; Col 1:16
3. They were all created at the same time. Heb 12:22 says there are “myriads” of them but since they cannot reproduce (Mt 22:30). . . .Col 1:16 also suggests a singular act of creation.
4. They are a higher order than man. Heb 2:7 says that angels are higher than men – even higher than Jesus while He was in the flesh. They don’t die (Lk 20:36) and have more wisdom than man (2:Sam 14:20). Their wisdom is limited though – certainly less than God’s (Mt 24:36). They have more power than men (Mt 28:2; Acts 5:19; 2 Pet 2:11) but it is still a limited power (Dan 10:13).
Some of the most prominent angels are:
Michael (Dan 10:13; 12:1; Jude 9)
Gabriel (Dan 9:21; Lk 1:26)
Lucifer (Is 14:12)
Some of the things that angels do include:
Serving God (Rev 5:11-12)
Ministry to Jesus (Lk 1:26-38; 22:43; Mt 2:13; 2:20; 4:11; 28:5-7; 1 Kgs 19:5-7; Acts 1:10; Mt 25:31)
Ministry to Believers
Protection (Ps 34:7; Acts 5:19; Rev 7:1-14)
Provision (1 Kgs 19:5-7)
Encouragement (Acts 27:23-25)
Direction (Acts 8:26; 10:3, 22)
Assist in answering Prayer (Acts 12:1-11; Dan 9:20-27)
Carry us home (Lk 16:22)
Serve God in Judgment (Rev 8:2-12; 9:1, 13; Mt 13:39-42)
How does this change my life? I believe it has and will continue to change my life every time an angel ministers to me as a believer. I am not aware of specific times when this has happened, but I do believe that it has. There are certainly countless times when I have been in need of protection, provision, encouragement, direction, and answered prayer and have received those things. I feel confident in saying that angels have probably had a hand in those situations. I also believe that their work in ministering to Jesus and in serving God have an affect on me – maybe not a direct impact, but that doesn’t mean anything. Also, by having this understanding of angels, I’ll be able to pray specifically for God to send angels when I find myself or my friends in need of these kinds of ministries.
