The clear implication of Leviticus 13:47-59 is that some, though not all, leprous garments became clean. Peter's vision of "all kinds of four-footed animals of the earth, wild beasts, creeping things, and birds of the air" (Acts 10:12) speaks to this point. God made it clear that He was capable of cleansing the Gentiles, but never said He had cleansed all of them at this time. Notice His admonition to Peter: "What God has cleansed you must not call common" (verse 15). Peter got the picture when he met Cornelius shortly after, telling the Roman centurion: "In truth I perceive that God shows no partiality. But in every nation whoever fears Him and works righteousness is accepted by Him" (verses 34, 35). While God calls from "every nation," only some, those who fear and obey, are acceptable to Him.
In verse 36, Peter interjects a vital idea: Christ "is Lord of all." Verse 45 records that the "Holy Spirit had been poured out on the Gentiles also." The "apostles and brethren who were in Judea" (Acts 11:1) came to understand that "God has also granted to the Gentiles repentance to life" (verse 18).
