We are not saved by trying, but by trusting in what Christ has done for us.
This means:
Repentance.
LET the wicked forsake his way (that’s your part), and the unrighteous man his thoughts (that’s your part): and let him return unto the Lord (that’s your part), and He will have mercy upon him; and to our God, for He will abundantly pardon (God’s part.).
Isaiah 55:7
Faith.
FOR by grace are ye saved through faith; and that not of yourselves; it is the gift of God: not of works, lest any man should boast.
Ephesians 2:8—9.
VERILY, verily, I say unto you, He that heareth My word, and believeth on Him (God) that sent Me (Christ), hath everlasting life, and shall not come into judgment, but hath passed out of death into life.
John 5:24. A.V. & R.V.
Receiving.
BUT as many as received Him (Christ), to them gave He power to become the sons of God, even to them that believe on His name.
John 1:12.
Committing.
COMMIT thy way unto the LORD; trust also in him; and he shall bring it to pass.
Psalms 37:5.
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. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
Romans 10:9-10.
