In Short

1

God chose his people from before the creation of the world because of his grace.

“He has saved us and called us to a holy life—not because of anything we have done but because of his own purpose and grace. This grace was given us in Christ Jesus before the beginning of time.”
2 Timothy 1:9-10

“So too, at the present time there is a remnant chosen by grace. And if by grace, then it cannot be based on works; if it were, grace would no longer be grace.”
Romans 11:5-6

“He chose us in [Christ] before the creation of the world to be holy and blameless in his sight. In love he predestined us for adoption to sonship through Jesus Christ, in accordance with his pleasure and will—to the praise of his glorious grace, which he has freely given us in the One he loves.”
Ephesians 1:4-6

God’s election does not mean he chose everyone else to be condemned in hell.

“‘As surely as I live,’ declares the Sovereign LORD, ‘I take no pleasure in the death of the wicked, but rather that they turn from their ways and live.'”
Ezekiel 33:11

“This is good, and pleases God our Savior, who wants all people to be saved and to come to a knowledge of the truth. For there is one God and one mediator between God and mankind, the man Christ Jesus, who gave himself as a ransom for all people.”
1 Timothy 2:3-6

“For the grace of God has appeared that offers salvation to all people.”
Titus 2:11

“For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.”
John 3:16

God’s election is meant to be a message of comfort for his people.

“In him we were also chosen, having been predestined according to the plan of him who works out everything in conformity with the purpose of his will, in order that we, who were the first to put our hope in Christ, might be for the praise of his glory.”
Ephesians 1:11-12

“I pray that the eyes of your heart may be enlightened in order that you may know the hope to which he has called you, the riches of his glorious inheritance in his holy people, and his incomparably great power for us who believe.”
Ephesians 1:18-19

“You are a chosen people, a royal priesthood, a holy nation, God’s special possession, that you may declare the praises of him who called you out of darkness into his wonderful light.”
1 Peter 2:9
