What is the difference between "outpouring of the Holy Spirit" and "filling of the Holy Spirit"?

Here is an example of a context with **"outpouring of the Holy Spirit"** (phrase in bold): > #### Bill McLeod > > Wilbert “Bill” Laing McLeod (1919 - 2012). Canadian Baptist pastor and revivalist born in Winnipeg, Manitoba. Converted at 22 in 1941, he left a sales career to enter ministry, studying at Manitoba Baptist Bible Institute. Ordained in 1946, he pastored in Rosthern, Saskatchewan, and served as a circuit preacher in Strathclair, Shoal Lake, and Birtle. From 1962 to 1981, he led Ebenezer Baptist Church in Saskatoon, growing it from 175 to over 1,000 members. Central to the 1971 Canadian Revival, sparked by the Sutera Twins’ crusade, his emphasis on prayer and repentance drew thousands across denominations, lasting seven weeks. McLeod authored When Revival Came to Canada and recorded numerous sermons, praised by figures like Paul Washer. Married to Barbara Robinson for over 70 years, they had five children: Judith, Lois, Joanna, Timothy, and Naomi. His ministry, focused on scriptural fidelity and revival, impacted Canada and beyond through radio and conferences. > > #### Sermon Summary > > In this sermon, the speaker shares a powerful testimony of a meeting where the glory of God was experienced. It started with one person praying and soon others joined, resulting in a powerful **outpouring of the Holy Spirit**. The meeting lasted for over four hours, with people confessing their sins and seeking God's presence. The speaker emphasizes the need for the glory of God to return to our churches and lives, and encourages repentance, prayer, faith, and identification with Christ as the simple yet costly price to pay for experiencing God's glory. > > https://www.sermonindex.net/sermons/XuEeri0s1gBZfmHq Here is an example of a context with **"filling of the Holy Spirit"** (phrase in bold): >#### God's Word Enhances the Work of the Spirit > >A beam of light doesn't have to shine down on my house for the Spirit to fill me. I don't have to jump three times and turn in circles or say the right thing or have the name John to know the power of the Holy Spirit. I simply need to pray, seek to align my heart with God’s, and fill my mind with His Word. > >It isn't complicated, but that doesn’t mean it’s effortless: a daily **filling of the Holy Spirit** requires a daily filling of the Word of God. In contrast, I firmly believe a lack of Spirit-filled living is due to a lack of enthusiasm for the Bible, along with mediocre attempts to fight sin. But if God's Word is filling us, then the Spirit of God will too. > > https://www.reviveourhearts.com/blog/what-does-it-mean-to-be-filled-with-the-spirit/ From the first context, **"outpouring of the Holy Spirit"** appears to convey the idea of a dramatic, identifiable event, one that might even be highlighted on a calendar.
