God the Father, Jesus, and the Holy Spirit are three distinct persons within one being (aka God).
We refer to this dynamic as the Trinity (or the Triune God).
It’s one of the most difficult biblical concepts for our human brains to grasp; we’ll never really understand on this side of heaven. But it’s a core biblical truth:

John 14:9-10 (MSG): “You’ve been with me all this time, Philip, and you still don’t understand? To see me is to see the Father. So how can you ask, ‘Where is the Father?’ Don’t you believe that I am in the Father and the Father is in me? The words that I speak to you aren’t mere words. I don’t just make them up on my own. The Father who resides in me crafts each word into a divine act.” [Said by Jesus.]
In John 10:30 (NLT), Jesus says it even more succinctly: “The Father and I are one.”
Matthew 28:19 (NLT) mentions the entire Trinity: “Therefore, go and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit.”

Jesus is not God the Father - but He is part of the Triune God.
In other words, He’s part of God (the overall being) – which means He loves us like God loves us.
Jesus wasn’t a good man who walked the earth 2,000 years ago and then died.
He’s part of the Trinity. This is why, when He was born into human history, He was referred to as the Son of God. Because He was God manifested into human form. Meaning, He was conceived by the Holy Spirit.
Which brings us to our second point….

Jesus is our Savior. He was born into human history to ultimately die on the cross, for our sins, so that we could be fully reconciled with God.

1 John 4:14 (NLT): “Furthermore, we have seen with our own eyes and now testify that the Father sent his Son to be the Savior of the world.”
John 3:16 (NLT): “For this is how God loved the world: He gave his one and only Son, so that everyone who believes in him will not perish but have eternal life.”

Now, it needs to be noted that even though verses such as these say that Jesus was “sent” by God the Father, it doesn’t mean that Jesus went to the cross against His will. Or that He was being abused by God the Father.
As we just looked at, Jesus is part of the Trinity. He’s a distinct persona of God just like God the Father and the Holy Spirit.
God the Father does have the ultimate authority. But Jesus has as much love for us as God the Father does. He’s just as invested in our welfare.
Jesus willingly went to the cross for us–and that is an insane act of love.
Because here’s the thing: sin cannot exist alongside God because He is holy. (In other words, He exists apart from all evil, wickedness, and sin.)
And as Romans 3:23 (NLT) says, “...all have sinned and fall short of the glory of God.”
This means that, after the fall back in the Garden of Eden when sin entered the world, we faced being separated from God for all eternity.
Rather than let this happen, and rather than place His wrath on us for our sins (because while He loves us, God hates sin because He is holy), in His love, grace, mercy, and goodness, God the Father created a plan that had Jesus come to earth to die for our sins instead.
And it’s the blood of Jesus that makes us clean in God’s sights and allows us to be in His presence.

Isaiah 1:18 (NLT): “Though your sins are like scarlet, they shall be as white as snow; though they are red as crimson, they shall be like wool.”
Psalm 103:11-12 (NLT): “For as high as the heavens are above the earth, so great is his love for those who fear him; as far as the east is from the west, so far has he removed our transgressions from us.”

Now, while Jesus died on the cross so that all humans would have the opportunity to be in relationship with God, it’s not an automatic gift. Nor is it something that God will push on us.
We need to, as individuals, decide to accept that Jesus died for our sins and confess Him as our Lord and Savior. Jesus is the only way to have eternal life and closeness with God:

John 14:6 (NLT): Jesus told him, “I am the way, the truth, and the life. No one can come to the Father except through me.”

But again, this is an extremely loving gift–planned by God the Father–that Jesus–part of the Triune God–lovingly participated in despite what it cost Him, that is available to anyone.
And the only so-called requirement is that a person accept this truth.

There’s no list of things someone needs to personally achieve before they can be reconciled with God.
Jesus isn’t demanding that you pay Him back in some way for all of His pain, torture, and death on the cross.
