God chose us in Christ as the church (Grk: ekklesia), the called out ones. God has chosen us in Christ to be holy before Him in love (Ephesians 1:4-8). God has chosen us in Christ, and in Christ alone.
In Bible days, a father chose a bride for his son, so God our Father chose the bride for His Son. The church is the bride elect of our Lord Jesus Christ.
God the Father has chosen us for Christ the Son. The chosen are all who are in Christ. All who repent and believe on the Lord Jesus Christ are elect. Our calling and election is sure in Christ alone (2 Peter 1:10-11).
God has chosen us in Christ alone, because only Christ can save sinners. He is the only one who died for sinners. He is the only one raised from the dead to justify sinners and save us from condemnation and eternal judgment. The Son of God is the only way to God our Father (John 14:6). Those who refuse to believe in Christ reject God's one and only way of salvation (Acts 4:12).
Scripture makes it clear that God chose us in Christ before the foundation of the world. God foreknew all who shall be in Christ (Romans 8:29-30; Ephesians 1:4). God knows all things, the end from the beginning. He foreknew his people before time began. God has chosen us in Christ alone.
