Peter (preached)
Acts 10
[31] And said, Cornelius, thy prayer is heard, and thine alms are had in remembrance in the sight of God.
[32] Send therefore to Joppa, and call hither Simon, whose surname is Peter; he is lodged in the house of one Simon a tanner by the sea side: who, when he cometh, shall speak unto thee.
[33] Immediately therefore I sent to thee; and thou hast well done that thou art come. Now therefore are we all here present before God, to hear all things that are commanded thee of God.
[34] Then Peter opened his mouth, and said, Of a truth I perceive that God is no respecter of persons:
[35] But in every nation he that feareth him, and worketh righteousness, is accepted with him.
[36] The word which God sent unto the children of Israel, preaching peace by Jesus Christ: (he is Lord of all:)
[37] That word, I say, ye know, which was published throughout all Judaea, and began from Galilee, after the baptism which John preached;
[38] How God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were oppressed of the devil; for God was with him.
[39] And we are witnesses of all things which he did both in the land of the Jews, and in Jerusalem; whom they slew and hanged on a tree:

[41] Not to all the people, but unto witnesses chosen before of God, even to us, who did eat and drink with him after he rose from the dead. (Acts 13:31)
[42] And he commanded us to preach unto the people, and to testify that it is he which was ordained of God to be the Judge of quick and dead.
[43] To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.
[44] While Peter yet spake these words, the Holy Ghost fell on all them which heard the word.(The gospel of their salvation, same Ephes 1:13)
Paul (preached)
1 Cr 15
1 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
4 And that he was buried, and that he rose again the third day according to the scriptures:
5 And that he was seen of Cephas, then of the twelve

Acts 10:41, 13:31)
6 After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep.
7 After that, he was seen of James; then of all the apostles.
8 And last of all he was seen of me also, as of one born out of due time.
9 For I am the least of the apostles, that am not meet to be called an apostle, because I persecuted the church of God.
10 But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me.
11 Therefore whether it were I or they, so we preach, and so ye believed.

2 Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood
of Jesus Christ: Grace unto you, and peace, be multiplied.
18 Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers;
19 But with the precious blood of Christ, as of a lamb without blemish and without spot:
20 Who verily was foreordained before the foundation of the world, but was manifest in these last times for you,
21 Who by him do believe in God, that raised him up from the dead, and gave him glory; that your faith and hope might be in God.
