What makes God happy? A more biblical question would be: What gives our heavenly Father pleasure?
Fortunately, there is a very clear answer in Ephesians 1: “He chose us in Him before the foundation of the world, that we should be holy and without blame before Him in love, 5 having predestined us to adoption as sons by Jesus Christ to Himself, according to the good pleasure of His will, 6 to the praise of the glory of His grace, by which He made us accepted in the Beloved.7 In Him we have redemption through His blood, the forgiveness of sins, according to the riches of His grace 8 which He made to abound toward us in all wisdom and prudence, 9 having made known to us the mystery of His will, according to His good pleasure which He purposed in Himself .”
Understand that here the apostle says twice that it pleases the Father to both choose his children out of the world and then to give us the grace to understand this blessed choice and adoption. Our Lord Jesus was also very clear on this. In His High Priestlyf Prayer in John 17, Christ seven times calls believers the gift of the Father to the Son.
This is very important. We evangelicals often focus on our personal unworthiness for salvation. And we always want to lift up the holiness of God. The great juxtaposition between our sin and God’s righteousness causes us to believe that there is simply no way that the Father could desire us and delight in us, but such is His love that He is able to take pleasure in drawing to Himself those who are, by nature, His enemies. This is the very nature of grace.
Receive this truth. If you belong to Jesus in true conversion, it is because it pleased the Father to choose you from before the foundation of the world. He knew every sin, every failure, every rebellion that we would commit–and still Jesus says that we are the gift of the Father to the Son.
Get used to it. God delights in us and He saved us not because of any grudging obligation, but because it pleased Him to do so. Live in that truth.
