Recognize our own sinfulness, and our need for a savior.Luke 18
13 And the publican, standing afar off, would not lift up so much as his eyes unto heaven, but smote upon his breast, saying, God be merciful to me a sinner.
14 I tell you, this man went down to his house justified rather than the other: for every one that exalteth himself shall be abased; and he that humbleth himself shall be exalted.
Romans 3
10As it is written: "There is none righteous, no, not one;
Romans 3
23for all have sinned and fall short of the glory of God,
Turn from our sins; repent.John 8
11 She said, No man, Lord. And Jesus said unto her, Neither do I condemn thee: go, and sin no more.
Acts 20
21I have declared to both Jews and Greeks that they must turn to God in repentance and have faith in our Lord Jesus.
Believe in Jesus Christ, that is the Son of God, and that he died for your sins on the cross and rose from the dead. John 3
16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
Romans 10
9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
It is through God's grace and His mercy that we are saved.
I should clarify that "believing in your heart" is a belief that is more than just lip service. It is a belief that makes Jesus Lord of our lives, and acknowledges Him as our Savior. As a result of putting our complete faith in Him, we follow Him. Works are a result of our salvation, not the cause.
