We understand that you may be feeling distanced from God, as if your prayers are not being heard. In the passage you shared, Isaiah 1:15, God is speaking to the nation of Israel about their hypocrisy. They were going through the motions of religion, but their hands were metaphorically "full of blood," meaning they were living in sin. This is a reminder that God does not listen to our prayers when we harbor sin in our hearts.
Firstly, let's address the fundamental aspect of prayer. It is only through the name of Jesus Christ that our prayers are heard by God. As it is written in John 14:6 WEB: "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" And in Acts 4:12 WEB: "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved." Therefore, it is essential to come before God in prayer, presenting ourselves as in need of Jesus, confessing his holy name. Prayers to Mary, an angel, or other saints are not biblical. Not including the name of Jesus Christ, Jesus, or Christ or an abbreviation such as IJN (In Jesus Name), then make sure to discuss this issue. It is only by the name of Jesus that we have access to God.
Now, let's consider the issue of sin. In Isaiah 59:2 WEB, it is written: "But your iniquities have separated you and your God, and your sins have hidden his face from you, so that he will not hear." Unconfessed sin can hinder our communication with God. If you feel like God is not listening, it might be time for some spiritual reflection.
Let's pray together:
"Father in heaven, we come before you in the name of Jesus Christ, confessing our sins and seeking your forgiveness. Lord, reveal to us any hidden sin that may be hindering our communication with you. We desire to have clean hands and a pure heart, that we may dwell in your presence and delight in your closeness O Lord.
Lord, we ask that you hear the prayers of ### and have mercy on them. Lord, show them the areas of their life that need your healing touch. Shine your light into the dark corners of their heart, that they may be cleansed by the blood of Jesus. Father, we desire to have clean hands and a pure heart, that we may dwell in your presence and delight in your closeness O Lord. You said in your word in Psalm 34:15 WEB, 'The eyes of Yahweh are on the righteous. His ears are open to their cry.' Let us strive to be righteous in Jesus Christ.
Lord, Jesus, we thank you for your sacrifice on the cross, and we receive your forgiveness and your grace. We ask that you guide ### and help them to live a life pleasing to you.
In Jesus' name, we pray. Amen."
Remember, God is faithful and just to forgive us our sins and to cleanse us from all unrighteousness (1 John 1:9 WEB). Trust in Jesus Christ and his finished work on the cross, and know that God hears your prayers. Revive your life with the Word of God daily and let God's Spirit guide you to all truth.
