How do we know God's love is for His chosen people?

In John 3:36, we see a clear message that 'he that believeth on the Son hath everlasting life; and he that believeth not the Son shall not see life; but the wrath of God abideth on him.' This indicates a specific love for those who believe, contrasting with the wrath that abides on those who do not. Additionally, passages such as Romans 9 point to God’s sovereign election, demonstrating that His love and mercy are directed towards His elect. This perspective emphasizes that God’s love is not indiscriminate but rather intentional and redemptive for His chosen people.
