English “by” in Romans 5:10 was translated from Greek preposition 1722 en correctly translated 1,902 times into English “in” as found in John 14:20-23 “At that day ye shall know that I am in my Father, and ye in me, and I in you” “He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him” “Judas saith unto him, not Iscariot, Lord, how is it that thou wilt manifest thyself unto us, and not unto the world”? “Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him”.
English “that day” emboldened in preceding paragraph is the “thousand years” of Revelation 20:4, 5 and 6 and 2Peter 3:8 and the “one day” of 2Peter 3:8 and “the day of the Lord” of 2Peter 3:10 and the “day” “he hath appointed” in Acts 17:31 and “the Lord’s day” of Revelation 1:10 and “the day of the Lord Jesus” of 1Corinthians 5:5 “To deliver such an one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus”. Think on prior bible verse relative to “For this is good and acceptable in the sight of God our Saviour” “Who will have all men to be saved, and to come unto the knowledge of the truth”. Ask yourself: is this rocket science? … or… is this irrefutable truth, in your face, directly from God unfiltered by the world’s 4,351 religions?
