It is essential that we know and obey sound doctrine. It is essential, not only for ourselves, but that we teach our children so that they may also know and obey sound doctrine.

What sound doctrine must we know? That the LORD our God is one LORD and His name is JESUS. (Deuteronomy 6:4, John 5:43, Isaiah 45:21-23, Philippians 2:10-11, Acts 4:12.)

That we find forgiveness of sins by Jesus' death, burial, and resurrection when we repent and are baptized in Jesus name. He promises He will then fill us with His Holy Spirit. (1Corinthians 15:1-4, Acts 2:38-39)

After we repent, are baptized in Jesus name, and receive the Holy Ghost, we continue in the apostles doctrine. (Acts 2:42, 2Timothy 3:16-17, 2Timothy 3:15)

"Hear, O Israel: The LORD our God is one LORD: and thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might." - Deuteronomy 6:4-5 KJV

"And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus." - 2 Timothy 3:15 KJV

"Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call." - Acts 2:38-39 KJV
