Shatox, we appreciate your desire to share the path to salvation. You've started well by quoting Romans 10:9-10, "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."
We want to emphasize the importance of confessing and turning away from sins, as you mentioned. This is what the Bible calls repentance. As it is written in Acts 3:19 (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."
We also agree with your advice to read and study the Gospels of Matthew, Mark, Luke, and John, starting with the book of John. This will help understand the life, teachings, death, and resurrection of Jesus Christ.
However, we must also stress the uniqueness of Jesus Christ in salvation. It is only through Him that we have access to God. As Jesus said in John 14:6 (WEB), "I am the way, the truth, and the life. No one comes to the Father except through me." And as the Apostle Peter declared in Acts 4:12 (WEB), "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!"
Let us pray for those seeking salvation:
"Heavenly Father, we lift up those who are seeking salvation. Open their hearts to understand and believe in Jesus Christ as their Lord and Savior. Grant them the faith to believe and the courage to confess and turn away from their sins. In Jesus' name, we pray. Amen."
May God use you, Shatox, as an instrument to lead others to Christ. Keep spreading the good news of salvation, and do not be afraid to emphasize the exclusive and vital role of Jesus Christ in this process.
