It is a fact that all who are chosen of God have been predestinated to be conformed to the image of His Son, the Lord Jesus Christ (Rom. 8:29). All who have been redeemed by His blood and born of the Spirit are to seek to bring their character and conduct into conformity to the character and conduct of Christ. This most certainly involves moral character and conduct, but it also involves our standard of judgment, our witness, and our motive. Consider these three ways in which we should always strive to be like Christ.
(1) Judging saved and lost based on God's testimony rather than Satan's lie. Christ never judged any person saved or lost based on outward appearance and reputation. He always judged righteous judgment based on God's testimony. He said of the Pharisees who appeared righteous unto men, "You are of your father, the devil" (John 8:44). Our way naturally is to look at a person's acts of disobedience and judge them lost or look at a person's acts obedience and judge them saved, but our Lord judged all who were either ignorant of or not submitted to His righteousness as the only ground of salvation as lost and their deeds as evil.
(2) Speaking peace only when there is peace based on God's testimony. Our Lord did not tell men and women they were saved apart from belief of the truth of the Gospel wherein His righteousness is revealed and repentance of dead works and idolatry. He told them the truth. This is the way He dealt with the religious Nicodemus in John 3 as well as the adulteress Samaritan woman in John 4. He confronted the religionists of His day with the light of the Gospel that exposed their lostness and the wickedness of their best efforts to establish a righteousness of their own. He knew this was their only hope of salvation.
(3) Seeking to obey God in all areas of worship, dedication, love, morality without legalism. God the Son became incarnate, obeyed the law, suffered, bled, and died on the cross of Calvary for two reasons the glory of His Father and the salvation of His sheep. We who believe are to follow Him in obedience to all the commandments God gives us, not in order to attain or maintain salvation, not to be entitled to Heaven, but because Christ has already attained all eternal blessedness for us by His righteousness alone. Our Lord always commanded God's children to obey the Father as motivated by grace and gratitude. He never promoted licentiousness in the name of liberty. He always promoted love to God and love to our neighbor without any legal threats of punishment or any mercenary promises of reward as if we could earn God's favor and fellowship.
