Our aim in loving our enemy is to bless him not curse him. “Bless those who persecute you; bless and do not curse them.” Our first and most urgent longing for our enemies is that they be blessed—that they repent and that they trust Christ and that his ransom pay all their debts and give them salvation. Yes, that is the goal. It’s the goal of this every true follower of Christ. Live so as to lead people into an enjoyment of the mercy of God. 

"But to each one of us grace was given according to the measure of Christ's gift." - Ephesians 4:7

Here the focus is on Christ's giving each believer varied grace. You are uniquely graced with Christ's gift. This means that you are not an accident in the body of Christ. When you received grace, it was because Christ gave it in a measure suited to his good purposes for you and for the body.

This verse lays the lay the foundation that every member is to be a minister to the body in verses 11–12. "Each of us" is given grace not according to the measure of our worth or merit, but according to the measure that Christ decided to give. Romans 12:6 says almost the same thing: "We have gifts that differ according to the grace given to us." Our different giftedness is owing to sovereign grace, bestowed according to the will of Christ, the head. The Head knows what is good for the body.
