What does the Bible say about God's call for salvation?

According to Scripture, specifically 1 Corinthians 1:9, God is faithful, and He calls His people to fellowship through Christ. This call is not merely an invitation; it is an effectual summons from death to life, as illustrated in the calling of Lazarus from the tomb. This powerful call is underpinned by God's foreknowledge and predestination, where He sets His love upon the chosen, as seen in Romans 8:30. This strong affirmation encourages believers to recognize their calling as part of God's sovereign plan of salvation.
