The simple answer:
If you have accepted by faith the gospel of Jesus Christ, that He was delivered for our offences, was buried, and was raised again for our justification, then indeed yes you are of the Elect.
There is no special formula or hidden message in the scriptures to identify the Elect of God. “Elect” is not a dirty word and should never be treated as one. “Elect” means “chosen or selected”, so it should carry a sweet smell that indeed we are chosen, selected, and most importantly loved by God.
Being of the Elect does have great benefits: He shall gather them up by His angels when the time is right [Matthew 24:31]; He has shortened the tribulation period [Matthew 24:24]; He shall not allow them to be deceived in the end [Mark 13:22]; He shall avenge them [Luke 18:7]; He will have no one lay charge upon them [Romans 8:33]; He knew us by foreknowledge, sanctified us by the Spirit, cleansed us by the blood of Christ [1 Peter 1:2]; and these are just a few. Read the Manual and you will find many, many more.
Being of the Elect does not authorize us to be proud: We are not given the authority or privilege to walk about with our chest held out and our nose in the air as if we have attained that which others have not. This is not a club or lodge whereby we have earned our title by works of the flesh. “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] We should be in a continual state of humility and obedience for the simple fact that God has chosen to give grace and mercy over justice.
Being of the Elect carries great responsibility: One is to love God with all their heart, soul, and mind [Matthew 22:37] and obey Him [Acts 5:29]; One is to love thy neighbor as thyself [Matthew 22:39] and thy enemies [Matthew 5:43-45], and forgive them [Ephesians 4:32; Matthew 18:22]; One is to spread the gospel by witnessing [Mark 16:15] and being a light in darkness [Matthew 5:16]. If we fail to be obedient, we shall be chastened of the Lord [1 Corinthians 11:32].
There is no reason to sit around and wonder if you are of the Elect or not. One needs only to obey scripture by putting their faith in the finished work of Christ. Don’t worry about if the Father is going to call you, whether the Spirit is going to convict you, and whether Christ will accept you. All one needs to do repent of your sin and come to Christ in faith believing He can take care of all the details!
