How do we know God hears our prayers according to the Bible?

The understanding that God hears our prayers is beautifully illustrated in the Bible through the name Simeon, which means 'hearing with acceptance.' In Genesis 29:33, Leah acknowledges that the Lord has heard her cries. This theme is consistent throughout Scripture, as seen in Exodus 3:7-8, where God reveals that He has seen the affliction of His people in Egypt and has come to deliver them. This shows that God is not only aware of our struggles but is actively involved in our deliverance. He hears our pleas for salvation and relief from sin's bondage, ultimately fulfilled in Jesus Christ.
