What does the Bible say about the Spirit of God filling believers?

In Judges 11:29-33, we see the Spirit of the Lord coming upon Jephthah, demonstrating that the Holy Spirit equips believers to accomplish God's will. This filling is not based on our efforts but is a sovereign act of God. Ephesians 4:7 explains that grace is given according to the measure of Christ's gift, meaning that the Spirit empowers each believer uniquely according to God's design. Furthermore, 1 Corinthians 12:11 highlights that the Spirit distributes gifts severally as He wills, emphasizing God's sovereignty in how He equips His Church.
