Note 1 at Acts 10:44: These Gentiles didn't go through any rituals, repeat any doctrinal statements, they hadn't been baptized yet, as some people teach that you must in order to be saved (see note 9 at Mk. 16:16, p. 564), and yet God gave them the Holy Ghost. A lost man cannot receive the Holy Ghost (see note 27 at Jn. 14:17, p. 491), therefore we see that the Lord granted salvation solely on the basis of the faith in their hearts.

Note 2 at Acts 10:44: In this instance, these Gentiles received the baptism of the Holy Ghost simultaneously with the new birth. In other cases, the Spirit baptism came later (see note 3 at Acts 8:16, p. 616). God, who knows the hearts of all men (Acts 1:24), must have seen that these men were ready for everything the Lord had for them, so He gave it to them all at once. The Lord is no respecter of persons (Rom. 2:11) and He will do the same for believers today.
