In his work on the Beatitudes, the puritan Thomas Watson makes the point early on that those who are saved, have many of the benefits of salvation here and now, not just in the future. (Actually it strikes me as odd to write that – there is a huge pressure to think in the opposite direction, as if all the benefits of salvation were only for here-and-now, and the future blessings more or less irrelevant, or too far into the future to think much about for the moment. I suppose the context is that most of the beatitudes in Matthew 5 are phrased in terms of ‘shall be’ – ‘Blessed are they that mourn, for they shall be comforted …’, as Watson himself would surely say it was a mistake to think too much in one direction or the other.)
Anyway, he gives a list of seven points in support of the statement that ‘the godly are blessed already,’ and the first in the list is, In that they are enriched with heavenly blessings (Eph 1:3).
“How are the saints already blessed? In that they are enriched with heavenly blessings, Ephesians 1:3. They are ‘partakers of the divine nature,’ 2 Peter 1:4, not by an incorporation into the divine essence, but by transformation into the divine likeness. This is blessedness begun. As the new-born babe is said to have life in it as well as he who is fully grown, so the saints, who are partakers of the divine nature, have an inchoate blessedness, though they have not arrived yet at perfection. Believers have the seed of God abiding in them, 1 John 3:9. And this is a seed of blessedness. The flower of glory grows out of the seed of grace. Grace and glory differ not in kind but degree. The one is the root, the other the fruit. Grace is glory in the dawning; glory is grace in the meridian. And in this sense that assertion of Augustine is true, ‘Blessed are we in faith and in hope.’ Grace is the first link in the chain of blessedness. Now he that has the first link of the chain in his hand, has the whole chain. …”
