God has predestined before the foundation of the world who would be saved (Calvinistic Soteriology).

Good Question. I think the fundamental misunderstanding to this question is this: you think that election is just and end. For some reason you are confused into thinking that there is no purpose past God's election and that isn't true. I am going to give you verses to prove that point and then I am going to use most of them, if not all of them, to prove a larger point. "For those whom he foreknew he also predestined to be conformed to the image of his son." Romans 8:29 "Even as he chose in him before the foundation of the world, that we should be holy and blameless before him." Ephesians 1:4 I'll give you one more. "But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession that you may proclaim the greatness of him who called you out of darkness and into his marvelous light." 1 Peter 2:9. All three of these verses show that there is a purpose to our election. That God didn't just choose us but he chose us for a purpose. So, from the basis that he chose us for a purpose, here are a few reasons that we attempt to understand and read the Bible: 1. Because of just the opposite of what you said. Salvation is at stake. We try to understand and read our Bibles for the sake of evangelism. God has chosen that the means in which the elect will come to faith is through the preaching and proclamation of the Word of God. 2. God created us to worship. 1 Peter 2:9. Jesus taught us to worship in spirit and in truth. For us to worship and to know his "excellencies" as 1 Peter 2:9 says, we must read, study and examine the Word of God. 3. God created us for purity. Romans 8:29 and Ephesians 1:4. Paul said in Phillippians 1:9-10 that, "it is my prayer that your love may abound more and more, with knowledge and all discernment, so that you may approve what is excellent and so be pure and blameless for the day of Christ." The key word in those verses is, "with knowledge." For us to grow in purity, we must grow in knowledge. For us to grow in knowledge, we must read the Word of God. I will end my simply quoting a very important passage of scripture in my opinion. John 1:1-14: In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that was made. In him was life, and the life was the light of men. The light shines in the darkness, and the darkness has not overcome it. There was a man sent from God, whose name was John. He came as a witness, to bear witness about the light, that all might believe through him. He was not the light, but came to bear witness about the light. The true light, which gives light to everyone, was coming into the world. He was in the world, and the world was made through him, yet the world did not know him. He came to his own, and his own people did not receive him. But to all who did receive him, who believed in his name, he gave the right to become children of God, who were born, not of blood nor of the will of the flesh nor of the will of man, but of God. And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth. Hope this helps.
