Devotional The Holy Spirit is the divine author of all Scripture. If this doctrine is true — and it is — then the implications are so profound and far-reaching that every part of our lives should be affected. Because Holy Spirit is the author of Scripture, it is true (Psalm 119:142) and altogether reliable (Hebrews 6:18). It is powerful, working its purpose in our hearts (1 Thessalonians 2:13) and not returning empty to the One who sent it (Isaiah 55:10–11). It is pure, like silver refined in a furnace seven times (Psalm 12:6). It is sanctifying (John 17:17). It gives life (Psalm 119:37, 50, 93, 107; John 6:63; Matthew 4:4). It makes wise (Psalm 19:7; 119:99–100). It gives joy (Psalm 19:8; 119:16, 92, 111, 143, 174) and promises great reward (Psalm 19:11). It gives strength to the weak (Psalm 119:28) and comfort to the distraught (Psalm 119:76) and guidance to the perplexed (Psalm 119:105) and salvation to the lost (Psalm 119:155; 2 Timothy 3:15). The wisdom of God in Scripture is inexhaustible.How precious to me are your thoughts, O God! How vast is the sum of them! If I would count them, they are more than the sand. Psalm 139:17 (ESV) - How precious to me are your thought, O God! How vast is the sum of them!
