We rejoice with you for sharing this good news and for pointing those who are searching to the only way of salvation. We agree that this is the most important message anyone can hear and we thank God for your heart to see others saved.
You have quoted Romans 10:9-10 which declares that 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 resulting in righteousness; and with the mouth confession is made resulting in salvation. We gently clarify the wording there so that all who read may understand clearly that it is confession with the mouth that Jesus is Lord and belief in the heart in His resurrection. We also affirm what you said about confessing and turning from sins, for true faith includes repentance. As it is written in Acts 3:19, Repent therefore, and turn again, that your sins may be blotted out, and in 1 John 1:9, If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness.
Salvation is by grace through faith in Jesus Christ alone. There is no other name by which we can be saved, for it is written in Acts 4:12, 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. Jesus himself said in John 14:6, I am the way, the truth, and the life. No one comes to the Father, except through me. And we are reminded in Ephesians 2:8-9, for by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, that no one would boast. Yet the faith that saves is a living faith that follows and obeys Jesus, taking up our cross daily and walking in newness of life as taught in Luke 9:23 and 2 Corinthians 5:17.
We fully agree with your encouragement to read and study Matthew, Mark, Luke, and John, beginning in the Gospel of John. In John we meet Jesus as the Word made flesh, the Lamb of God who takes away the sin of the world, and we read the promise of John 3:16, For God so loved the world, that he gave his one and only Son, that whoever believes in him should not perish, but have eternal life. As Jesus said in John 8:31-32, If you remain in my word, then you are truly my disciples. You will know the truth, and the truth will make you free.
We join together and pray for every person who is looking for salvation and reading these words. Father, we come before you in the name of Jesus Christ, and we ask that you draw each searching heart to yourself. Open their eyes to see their need for a Savior, grant them godly sorrow that leads to repentance, and give them faith to confess with their mouth that Jesus is Lord and to believe in their heart that you raised Him from the dead. Forgive their sins, cleanse them from all unrighteousness, and make them new creations in Christ. Fill them with your Holy Spirit and give them hunger for your Word, especially the Gospels, that they may know Jesus, follow Him, and obey Him all the days of their lives. Lead them to fellowship with other believers who will help them grow in truth and grace. We ask this in the precious and powerful name of Jesus Christ, our Lord and Savior, amen.
