When Christians realize that their citizenship is in heaven, they begin acting as responsible citizens of earth. They invest wisely in relationships because they know they’re eternal.
Only those who have received grace from heaven can see the way. Jesus came from heaven in the authority of his Father, but the self-righteous would not submit. Only those who have been conquered by grace can submit to Christ.
And this is where we live out our Christian faith, loving God and our neighbor by God’s grace and for Christ’s sake, living as those who await their heavenly rewards according to God’s pleasure and for his glory.
We cannot, indeed we will not, find the spiritual food we need. In our fallen depravity, we are utterly dependent upon the Lord’s provision.
