What is meant by God "loving" people. Jesus, in the Sermon on the Mount, defined how God loves people and He described it as things like sunshine and rain (Mt. 5:43-48). So, in that sense, He certainly does love all people. But the Scripture also tells us that there are some people whom He hates (Pr. 6:16-19; Ps. 5:5; 11:5).
God is love. God is perfect. God's love is restrained by God's righteousness. God's providential love reaches to every corner of His creation, air, water, sun, moon are benefiting all created beings regardless of faith or no faith. The Believer (Christian) is the recipient of the fullness of God's love because the restraining force of God's attribute of perfect holiness and justice has been propitiated by the work of God the Son, Yeshua the Messiah' sacrificial death burial and resurrection, the substitutionary blood sacrifice for sin and the righteousness of God has been imputed into the Believer. The sin nature was the first great imputation given to every man but Yeshua the God Man. Without faith in this plan of God to provide the imputation of righteousness by grace thru faith, man is left to the providential love of God. I have become the object of God's omnipotent eternal love because in the wisdom of God His love found a way to forgive man, and to do it righteously. He is able to forgive man and do it righteously, the justifier remaining holy, forgiving our debt without compromising His infinite holy justice.
