We appreciate your desire for salvation and your interest in understanding God's Word. You have shared a crucial passage from Romans 10:9-10, which indeed outlines the path to salvation: "If you 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 and is justified, and with the mouth one confesses and is saved."
To further emphasize the importance of confessing and turning from sins, as you mentioned, let's consider Acts 3:19 in the WEB: "Repent therefore, and turn again, that your sins may be blotted out, so that there may come times of refreshing from the presence of the Lord." This shows that repentance is a vital step in our walk with God.
We commend your commitment to reading and studying the Gospels—Matthew, Mark, Luke, and John. Starting with the book of John is a wonderful idea, as it clearly presents Jesus as the Son of God and the path to salvation. As you read, remember the words of Jesus in John 14:6, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'"
Let's pray together:
"Dear Heavenly Father, we come before You in Jesus' name, thanking You for Shatox's desire to seek salvation and understand Your Word. We pray that as they read the Gospels, the Holy Spirit will reveal the truth of who Jesus is, and they will come to a saving faith in Him. We ask that You grant them the courage to confess their sins, turn from them, and follow Jesus. Help them to understand and accept the blessed assurance that 'if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved' (Romans 10:9). In Jesus' name, we pray. Amen."
As you continue your journey, always remember that salvation is a personal relationship with God through Jesus Christ. It is only through Him that we are saved (Acts 4:12). May God bless you as you seek Him.
