We do not live only for our biological family but also for the family of God and to those who are not yet part of the family of God for them to be part of it. We remain in flesh and we must be fruitful, like the church of Philippi and that fruitfulness is through obedience and is crucial in bringing people into God’s family, into His kingdom.
In short, to live is Christ! to proclaim to those who are already redeemed that they are now to be reclaimed in Christ.
To proclaim the gospel is worth living and dying for above any other cause!
