How do we know Christ will save those who come to Him?

In John 6:37, Jesus clearly states, 'All that the Father giveth me shall come to me, and him that cometh unto me I will in no wise cast out.' This promise establishes the security of salvation in Christ. The doctrine of sovereign grace teaches that those who are given by the Father to the Son will inevitably come to Him, recognizing their need for salvation. The assurance in Christ’s words highlights His commitment to save those who are drawn to Him by the Holy Spirit, reinforcing that the lost sinner’s trust in Jesus is met with grace and acceptance. This truth reassures believers that their hope does not rest on their ability to sustain faith, but rather on Christ's unwavering promise.
