Missions is not the ultimate goal of the church. Worship is. Missions exists because worship doesn't.

You can't praise what you don't prize.

According to the spirit of this age, the ultimate sin is no longer the failure to honor and thank God but the failure to esteem oneself. Self-abasement, not God-abasement, is the evil. And the cry of deliverance is not "O wretched man that I am, who will deliver me?" but "O worthy man that I am, would that I could only see it better"!

If you are sufficient for your task, it's too small.

Redemption is not perfection. The redeemed must realize their imperfections.

Not to abide in Jesus’ love would mean that we stop believing that we are loved by Jesus. We look at our circumstances - perhaps persecution or disease or abandonment - and we conclude that we are not loved by Jesus anymore. That’s the opposite of abiding in the love of Jesus. So abiding in his love means continuing to believe, moment by moment, that we are loved.

So saving grace, converting grace, for Augustine, is God's giving us a sovereign joy in God that triumphs over all other joys and therefore sways the will. The will is free to move toward whatever it delights in most fully, but it is not within the power of our will to determine what that sovereign joy will be.
