We Christians sometimes think more highly of ourselves than we should, just because we have come to the knowledge of our salvation as the firstfruits of the harvest. It should humble us, not make us see ourselves as more favorable to God than others who have not been given this knowledge yet. God is the Father of ALL, and His Son Jesus is Lord of ALL.  Together they will Save ALL, and ALL men will eventually have this knowledge.

"...yet for us there is but one God, the Father, from whom are all things and we exist for Him; and one Lord, Jesus Christ, by whom are all things, and we exist through Him. However not all men have this knowledge ..." (1 Corinthians 8:6-7)

God is no respecter of persons. All sinners will be saved at the proper time because that is what Christ Jesus came to do. And apparently the worst sinners are saved first.

"It is a trustworthy statement, deserving full acceptance, that Christ Jesus came into the world to save sinners, among whom I am foremost of all... God our Savior...desires all men to be saved and to come to the knowledge of the truth... Christ Jesus, who gave Himself as a ransom for all, the testimony given at the proper time.…" (1 Timothy 1:15-2:6)

Again, the Scripture is clear that God is the Father of ALL and ALL will come to be in unity of the faith when, "at the proper time" they come to "the knowledge of the Son of God." In the meantime, be kind to people, if they let you.

"...One God and Father of ALL, who is above all, and through all, and in you ALL... Till we ALL come in the unity of the faith, and of the knowledge of the Son of God... be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you." (Ephesians 4)
