<p>4:30 <i>And do not grieve the Holy Spirit of God, by which you were sealed until the day of redemption</i>- All the bad behaviour of :19-29 is at variance with the Spirit which has been given to each believer, and which seeks to bring forth in us spiritual behaviour. But we are grieving or effectively frustrating this process if we refuse to be transformed. The gift of the Holy Spirit is in our hearts- God has &quot;sealed us and given the earnest of the Spirit in our hearts&quot; (2 Cor. 1:22). This gift of the Spirit is the foretaste of our final redemption (2 Cor. 5:5). After we believed, we were given this promised gift of the Spirit (1:13). Those who lied, stole and swore were given it. But by remaining in the old life and ways, they were not allowing it to function. The allusion is to how Israel in the wilderness had been baptized in the Red Sea and yet they grieved God's Spirit (Is. 63:10) in the form of the Angel who wished to lead them to the Kingdom of God.&nbsp;</p><p>The &quot;Holy Spirit&quot; may allude to a specific Angel set apart for this purpose of strengthening us so that we might reach the Kingdom, like the wilderness Angel provided Israel with the manna (= the word of God, so the Lord Jesus reasons in Jn. 6) and every type of sustenance in order that they should get through the wilderness to the promised land. In the same way, the Holy Spirit is associated with our calling and choosing. The Angel was associated with the sealing of the believers (Rev. 7:2,3). We must not &quot;grieve the Holy Spirit of God (cp. how Israel vexed the Holy Spirit Angel- Is. 63:10) whereby ye are sealed&quot;. Eph. 4:30 also links this grieving the Holy Spirit (referring to the Holy Spirit Angel of Is. 63:10) and abusing God's sealing of us, as if by the unspiritual behaviour Paul is speaking of in Eph. 4 we will truly grieve or sadden the Angel who has sealed us.</p>
