Many people picture their guardian angels standing next to them. The Lord says that our angels are sent before us. This means our guardian angels are advance guards because we as members of Christ's body are advancing His kingdom.
If someone asked us what our guardian angels said to us today, many of us would be surprised that guardian angels can talk. However, the Lord clearly commands us in reference to each one's guardian angel: "Be attentive to him and heed his voice" (Ex 23:21).
What do guardian angels say? They give us commands from God, and we are tempted to rebel against them and God (Ex 23:21).
How do guardian angels guard us? Do they shield us, push people out of our way, or keep us from falling? Our guardian angels go before us and wipe out several nations like "the Amorites, Hittites, Perizzites, Canaanites, Hivites and Jebusites" (Ex 23:23).
When we picture our guardian angels properly, we better understand God's nature, His plan, and our surprisingly important and powerful part in His plan (see Heb 11:40). In Christ, live the life that needs all that guardian angels can do.
