<p>4:19 <i>And my God shall supply every need of yours according to His riches, in glory in Christ Jesus</i>- This is a tacit recognition that Paul did have material needs, although he discounts them. He understands &quot;riches&quot; to refer to spiritual blessings given through the gift of the Spirit in the inner man (Eph. 1:7; 3:16). The &quot;riches in glory&quot; is the term used in Rom. 9:23 and Eph. 1:18 for our final salvation. The response to such generosity was going to be eternal. This is not to say that we can buy our salvation, but all the same, there will be an eternal outcome of generosity. And in this life too, the gift of the Spirit is given as a foretaste and guarantee of that great salvation in the future. Paul has used the idea of &quot;supply&quot; earlier, writing of &quot;the supply of the spirit of Jesus Christ&quot; (1:19). That supply of the Spirit, that great spiritual richness, would be granted in response to their giving; for grace, giving, <i>charis</i>, the gift of the Spirit, would be God's response to their giving. &quot;Supply&quot; is the same word just used in :18 for &quot;full&quot;. As Paul had been filled with their gift, so God would fill them with the Spirit and all its rich blessings. For the same word is in Eph. 5:18: &quot;Be filled with the Spirit&quot; (as Rom. 15:13 &quot;the God of hope <i>fill </i>you... through the power of the Holy Spirit).</p>
