The reason a person comes to Jesus is because the Father has first chosen to give him to Jesus, and none of those chosen for salvation will fail to come. Clearly, human beings do not have ultimate veto power to overthrow the saving will of God. Predestination is God-centered Because God is the most valuable and worthy being in the universe, the goal of God in everything He does is to glorify Himself. If He did not ultimately act for His glory in all things, He would not be righteous. This is because He would be placing the value of something else above the infinite worth of His glory.
Predestination is no different.
But God seeking His own glory in all things is not unloving. Even in loving us, the superior value of God's worth is magnified. Therefore, if we do not have a proper understanding of election, we will not have a proper understanding of the way God loves us. Further, God's love for His children has had no beginning and will have no end. He did not start loving you when you were born, but if you are one of His sheep, He has loved you eternally.
