The sovereignty of God in the salvation of men is seen as all members of the Trinity work to bring it about. God the Father chooses certain men to be saved (Ephesians 1:4), and His choice is unconditional. That is, He does not first look ahead into the future to see if a man would choose Him. God's choice is not on the basis of the efforts/ work of men (Romans 9:11, 16; John 1:12-13), but is instead according to the counsel of His own will. His choice is designed to bring Him all of the glory (Ephesians 1:5-6)
Practical application: The church must be moved to worship God for every man that is saved. Ephesians 1:14 says that redemption is for the "praise of His glory." When people are saved through the ministry of the church, there should be joyful praise and thanksgiving to God!
The church must recognize the sovereignty of God in salvation in all efforts of evangelism. The servant of God presenting the gospel must find his hope and confidence in the God who saves, not in methods, their own skill in presenting facts or arguments, or in their ability to convince a guilty sinner to pray a prayer. As well, he must serve His Lord prayerfully. As he prays for the salvation of souls, he expresses his complete dependence on God to grant a sinner repentance.
