Acts 2:25-30
Acts 2:25 (KJB)
For David speaketh concerning him, I foresaw the Lord always before my face, for he is on my right hand, that I should not be moved:
I shouldÖbe moved - Shaken, totter, or falter
Peter now begins a four verse quotation from Psalm 16. (Psa 16:8 KJV) I have set the LORD always before me: because he is at my right hand, I shall not be moved.  David was prophesying the events which happened in Jerusalem but through a different interpretation. David was stating that the Lord was always with him to establish his throne and to be the strength of Israel. Therefore with the Lord as his strength, he would never be moved. David would always be stable in his walk and in the place the Lord had placed him and because of the Lordís strength, there would never be any wavering. The person that David was alluding to was the Lord Jesus Christ as we learn through Peterís sermon. The Lord Jesus Christ was the strength of Israel and He is also the strength of every single believer and as a result of His keeping power, we shall never be moved from Him. (1 Pet 1:5 KJV) Who are kept by the power of God through faith unto salvation ready to be revealed in the last time. Later in Peterís first epistle, he restates the same principle in different terms.
Acts 2:26 (KJB)
Therefore did my heart rejoice, and my tongue was glad; moreover also my flesh shall rest in hope:
(Psa 16:9 KJV) Therefore my heart is glad, and my glory rejoiceth: my flesh also shall rest in hope. Since the Lord Jesus Christ was the strength of Israel, David had rejoiced in his heart and was able to speak glad tidings of the relationship he had with the Lord. David was established and protected thorough the power of the Lord Jesus and not only was he able to speak great things of the Lord, he was also able to rest in hope. The hope that David had was the same hope which every true believer has and that is we are saved through the Lord Jesus Christ and kept by His power and for that reason we also rest in our flesh knowing that nothing can touch us or harm us unless God allows it to happen. (Psa 4:7-8 KJV) Thou hast put gladness in my heart, more than in the time that their corn and their wine increased. {8} I will both lay me down in peace, and sleep: for thou, LORD, only makest me dwell in safety. The Lord takes a hell bound sinner who walks in sorrow and when He saves them, He puts gladness in their heart. Psalm 96 calls it a new song. Not only does He put gladness in their heart, they can now sleep in peace, which means that they are secure enough in the Lord to watch over them at the most vulnerable time, which is when a person is asleep. They can confidently relinquish all anxieties to the Lord.
Acts 2:27 (KJB)
Because thou wilt not leave my soul in hell, neither wilt thou suffer thine Holy One to see corruption.
(Psa 16:10 KJV) For thou wilt not leave my soul in hell; neither wilt thou suffer thine Holy One to see corruption. Here David hits on two major topics concerning resurrection. First, David was assured that he would see the resurrection of his own body because of his tremendous faith in God, he would be unable to reconcile the fact that God is a living God who has guided and strengthened him, but would eventually abandon him? Perish the thought! David was basically giving an Old Testament understanding of the resurrection. Then David gives a prophecy of the resurrection of the Lord Jesus Christ. Jesus went into the tomb on Friday about 3 PM and was resurrected very early in the morning on Sunday. (Luke 24:1 KJV) Now upon the first day of the week, very early in the morning, they came unto the sepulchre, bringing the spices which they had prepared, and certain others with them. The body of the Lord Jesus Christ was in tomb only a short while and his body was not physically dead long enough to start corrupting. God had accepted the sacrifice of the Lord Jesus on behalf of the Elect and was resurrected to life and eventually ascended into Heaven having completed His earthly task.
Acts 2:28 (KJB)
Thou hast made known to me the ways of life; thou shalt make me full of joy with thy countenance.
(Psa 16:11 KJV) Thou wilt show me the path of life: in thy presence is fulness of joy; at thy right hand there are pleasures for evermore. David now speaks that God has shown him the true ways of life and that it is not tied to this world with riches and power but the ways of life are found in the Lord Jesus Christ. Life without Christ in this world ends up in eternal damnation in the next but the true way of life in Christ, is a life which never ends. Psalm 16:11 points to the fact that there are pleasures for ever more at the Lordís right hand. This means that once this world is over and the new one begins, no more will the believer be harassed by sin, sickness, temptation or the kingdom of Satan. There will be purity in the New Heaven and the New Earth along with joys that can never be hampered by sin again. The countenance of God will be joyful toward His redeemed children. It is going to be a glorious eternity for the believer.
Acts 2:29 (KJB)
Men and brethren, let me freely speak unto you of the patriarch David, that he is both dead and buried, and his sepulchre is with us unto this day.
Peter continues his sermon on David and the fact that Davidís tomb is still with them today. Davidís body was still entombed and would be until the last day when he too would experience the resurrection and reuniting of his body and soul. Right now David is in his spirit essence in Heaven awaiting the last day, the consummation of the ages. In this verse, Peter is also making a comparison between Jesus and David. The fact is that one can find the body of David but one cannot find the physical body of the Lord Jesus Christ. What Peter has been presenting to the people in Jerusalem was the fact of the resurrection of Christ and salvation through Him couched in an old Testament prophecy written about a thousand years prior. Peter was showing them that the Hebrew Scriptures were replete with references to the Lord Jesus Christ and those prophecies which were written over the course of hundreds of years were fulfilled in Christ in about a 33 year period.
Acts 2:30 (KJB)
Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, according to the flesh, he would raise up Christ to sit on his throne;
David was not only a king of Israel but he was also a prophet. We saw a portion of his prophecies from Psalm 16:8-11 which were really prophecies of the Lord Jesus Christ. Peter now furthers the credentials of David as he states that God had sworn an oath, that there would be a direct descendant of David to sit upon his throne. Some may think that this might have been Solomon who followed David as the third king of Israel. As we see in this verse, it was not an earthly king which is in view. Here we see that it is the Lord Jesus Christ would sit upon the throne of Israel. David was in the physical lineage of the Lord Jesus Christ. What throne was he talking about? Since David was a type of Christ and sat on the throne of physical Israel, it could not be a physical throne. What we are seeing here is the eternal throne where Christ will rule over all His children, who are known as spiritual Israel, those who have been redeemed through the blood of Christ. (2 Sam 7:15-17 KJV) But my mercy shall not depart away from him, as I took it from Saul, whom I put away before thee. {16} And thine house and thy kingdom shall be established for ever before thee: thy throne shall be established for ever. {17} According to all these words, and according to all this vision, so did Nathan speak unto David. Christ ruling over the house of David is known as the Davidic covenant. It speaks about the throne of David being established forever which completely deletes any type of physical throne. What is in view is eternal salvation.
