God's love for His People is perfect for those whom it intended to save

..."Preaching the gospel, he tells us, is not a matter of telling the congregation that God has set His love on each of them and Christ has died to save each of them, for these assertions, biblically understood, would imply that they will all infallibly be saved, and this cannot be known to be true. The knowledge of being the object of God’s eternal love and Christ’s redeeming death belongs to the individual’s assurance, which in the nature of the case cannot precede faith’s saving exercise; it is to be inferred from the fact that one has believed, not proposed as a reason why one should believe." - J.I. Packer


In other words because I am regenerated and justified and am being sanctified to believe is the fact that God did love me; that God did atone for my sins. John 3:16 - Are you believing now? For God loved the world in this way (qaulitatively) by giving up His son Jesus Christ so that any believing one will not perish but have eternal life. Christ actually took upon himself the due punishment that the sinner deserved, if the sinner on the one hand did not believe and was cast into the firey lake then it was because Christ did not atone for His sin.
