How do we know if our prayer is being heard by God? Bonus points for Bible references?

See these

Proverbs 15:29 — The LORD is far from the wicked, but he hears the prayers of the righteous.

James 5:16 KJV — Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much.

God hears the prayers of those who believe in Jesus and are faithful and trust God.

Those people know that God hears their prayers for they will feel and see the result.

John 9:31 "Now we know that God heareth not sinners: but if any man be a worshipper of God, and doeth his will, him he heareth."

Proverbs 15:29 "The LORD is far from the wicked: but he heareth the prayer of the righteous."

God listens to all of our prayers, regardless of what we ask (Matt. 7:7). He does not ignore His children (Luke 18:1–8). When we talk to Him, He has promised to listen and respond (Matt. 6:6; Rom. 8:26–27). His answer may be some variation of “yes” or “no” or “wait, not now.”

The truth is that death leads to heaven or hell, and the only way to heaven is through faith in Jesus Christ.

The Bible is very clear that no one can earn their way to heaven since good works do not pay for sins. See Gal. 2:16, Rom. 3:23-28, 4:4-5, Eph. 2:8-9, Tit. 3:5. The only way to heaven is by believing in Jesus for His free gift of eternal life. Jesus shed His blood on the cross as the full payment for our sins. He did all the work; all He requires of us is that we believe in Him. Once you believe in Jesus Christ to save you, you are secure forever!

Because we have all sinned against a perfectly holy and righteous God, we all deserve eternal separation from God in hell (Rom. 6:23). However, God loves us so much that He sent His only Son Jesus to die on the cross as our Substitute so we don't have to go to hell. Christ died for our sins, was buried, and rose from the grave three days later (1 Cor. 15:3-4). He gives eternal life freely to anyone who simply believes in Him for it. No one can be saved by doing good works. Salvation is by grace alone through faith alone in Christ alone (Eph. 2:8-9).

"Verily, verily, I say unto you, He that believeth on me hath everlasting life" (John 6:47).

Since all gods are myths I can guarantee you it doesn't.

1Pe 3:12 For the eyes of the Lord are over the righteous, and his ears are open unto their prayers: but the face of the Lord is against them that do evil.

now how do you know you are living a righteous life?

(the bible that's how)

love GOD

love others?

try to not sin....

repent as needed if you do?

this is living right.

loving GOD means trying to please HIM. (at all times)

understand?

You don't know.

By realizing no gods exist you can know none of them are hearing any prayers.
