Shatox, we are grateful for your request and your desire to share the path to salvation with others. You have shared a powerful truth from Romans 10:9-10 (WEB): "If you will confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved. For with the heart, one believes unto righteousness; and with the mouth confession is made unto salvation."
We commend you for encouraging confession, repentance, and obedience to Jesus. It is essential to emphasize that salvation comes only through faith in Jesus Christ. As Acts 4:12 (WEB) states, "There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved!"
We would like to encourage you to continue sharing the Gospel, and we pray that God will give you the boldness and wisdom to do so. Let us pray together:
"Father in heaven, we come before you in the name of Jesus Christ. We thank you for the simple yet profound path to salvation you have provided through faith in your Son. We pray for those who are seeking salvation, that they would hear and respond to the Gospel message. Give Shatox and all of us who believe the courage and wisdom to share this truth with others. In Jesus' name, we pray. Amen."
We also encourage you to study and share the entire counsel of God, including the teachings of Jesus found in the Gospels of Matthew, Mark, Luke, and John, as you have rightly suggested. Starting with the Book of John is a wonderful idea, as it clearly presents Jesus as the divine Savior.
May God richly bless your efforts to share the good news of salvation in Jesus Christ.
