where does the bible say this?
trinity is not mentioned anywhere in that scripture, it only speaks of worshiping the Father who Jesus says is one.

The Resurrection is right at the heart of the Christian faith. We celebrate the fact that our Savior is risen and has defeated death. The power of God is on full display in the Resurrection since each person raised Jesus from the dead, thus proving the fact God is Triune. This also refutes the notion the Trinity is made up of three gods (like Mormonism teaches), or that the Trinity is unbiblical (like Jehovah’s Witnesses teach).
One of the easiest ways to prove the Trinity biblically to the cults is to ask cultists if they believe God raised Jesus from the dead. They will agree with you because it is a biblical truth (Acts 2:24, 32; Rom. 10:9; 1 Pet. 1:21). However, the Bible clearly states that each person of the Godhead raised Jesus from the dead.
First, Scripture plainly states that the Father raised Jesus from the dead (Gal.1:1; Eph. 1:20). The JWs or LDS have often heard God or the Father raised Jesus from the dead but not the other members of the Trinity. But to avoid confusion, emphasize that God raised Jesus from the dead (Rom. 10:9). When the Bible says God raised Jesus from the dead, it is often referring to all three members of the Trinity. This is true throughout the Bible, unless it specifies which person. Emphasize this when talking to non-Trinitarians so they do not think you are advocating that Jesus is the Spirit or the Father.
Remember, in addition to the Father, the Son played a role in the Resurrection. Jesus declared He would raise Himself from the dead. After cleansing the temple in John 2, Jesus was questioned by the Jews for a sign after declaring the temple to be His Father’s house and purging it of vendors:
Jesus answered and said to them, “Destroy this temple, and in three days I will raise it up.” Then the Jews said, “It has taken forty-six years to build this temple, and will You raise it up in three days?” But He was speaking of the temple of His body. Therefore, when He had risen from the dead, His disciples remembered that He had said this to them; and they believed the Scripture and the word which Jesus had said (John 2:19-22,NKJV).
Notice that Jesus does not give glory to any other when declaring He would raise Himself from the dead. The common objection to these powerful verses is that Jesus is using symbolic language. However, notice verse 21 of John chapter two: “He was talking about the temple of His body”—the “temple” He would raise up in three days was His body. The Apostle John specifically wrote verse 21 so the reader would understand Jesus was declaring that He would raise Himself up physically from the dead because He was God.
Last, the Spirit also raised Jesus from the dead. In Romans 8:9-11, we read the following:
But you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. Now if anyone does not have the Spirit of Christ, he is not His. And if Christ is in you, the body is dead because of sin, but the Spirit is life because of righteousness. But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ from the dead will also give life to your mortal bodies through His Spirit who dwells in you.
Here we read God the Holy Spirit raised Jesus from the dead, and this same Spirit dwells in all believers. Thus, we have strong evidence from Scripture, when describing the Resurrection, that the Triune Godhead raised Jesus from the dead.
Each person of the Trinity played a part in the Resurrection, yet collectively the same essence of God raised Jesus from the dead. Note, unbelievers will often ask how Jesus could raise Himself from the dead if He died on the cross. Kindly point out to them that only his body died and His spirit was still alive. Show them how Jesus told the thief on the cross He would see him in paradise the same day they were crucified (Luke 23:43), so his spirit had not ceased to exist.
