Is it wrong to try to talk to your Guardian Angel?

Yes, we can talk to angels. Many people have spoken to angels including Abraham (Gen 18: 1-19: 1), Lot (Gen 19: 1), Balaam (Num. 22 :), Elijah (2 Kings 1:15), Daniel (Dan. 9: 21-23), Zechariah (Luke 1: 12-13 and also the mother of Jesus (Luke 1: 26-34). The angels of God assist Christians (Hebrews 1:14).

When the prophet Daniel spoke to Gabriel, the archangel, it was the angel who started the conversation.

And I heard the voice of a man on the shores of Ulai, and he called and said, "Gabriel, give this man an understanding of the vision." Then he approached where I was, and when he came I was frightened and fell on my face; but he said to me, "Son of man, understand that the vision belongs to the end time." (NASB) Daniel 8: 16-17

On another occasion, Daniel saw another angel who looked like a man.

Then this with the human aspect touched me again and strengthened me. And he said, "O man of great esteem, don't be afraid." (NASB) Daniel 10: 18-19

Both times Daniel was afraid. The angels who appeared to Abraham appeared as men (Gen 18: 1-2; 19: 1). Hebrews 13: 2 says that some people spoke to angels and did not know it. This means that you may have already spoken to an angel. Why should God do it? Why would God allow us to meet an angel and not let us know? The answer is that meeting an angel isn't that important. Otherwise God would make sure we knew it.

What should I say?
The answer to your question is: "Speak openly and honestly." For example, since we can meet an angel and not know that the person is an angel, do we know when to be careful with our words? When Abraham met three angels, he had a normal conversation. When the priest Zacharias spoke with an angel, he sinned with his words and was punished as a result (Luke 1: 11-20). What should we say? Speak the truth at all times! You never know who you're talking to.

There is enormous interest these days in angels. A person can purchase angel figures, books on angels and many other objects related to angels. Many of the things that are sold are simply the companies that take your money. But there is a more serious side. The occult and the New Age are also interested in angels. But these angels are not the holy angels of God, but demons who pretend to be good.

So is it wrong to want to talk to an angel? Scripture never says it is wrong to talk to one, but that doesn't mean we should want to do it. There are dangers in seeking supernatural experiences, because one could talk to a demon or Satan since he can even appear like an angel!

. . . for even Satan disguises himself as an angel of light. (NASB) 2 Cor. 11:14

He is a master of disguises. I can suggest that if the Lord Jesus wants you to talk to one, He will make that happen. It is wrong to worship angels, and many people today worship them in their desire to meet one (Col 2:18). Worship does not simply come down to one. Worship can include concern for angels.

Conclusion:
There is also the danger of wanting to know your guardian angel, just as it is dangerous to want to talk to one. What we should talk to is God. Is your desire to speak with an angel as strong as your desire to speak to God? Prayer is a supernatural experience with God. This is more powerful and important than talking to an angel because angels cannot do anything for me without their master's permission - God. God is the one who can answer my prayers, heal. my body, satisfy my needs and give me spiritual understanding and guidance. The angels are his servants and they want us to give glory to their Creator, not to themselves.
