I believe that the word of God is what is heard. Scripture is what is written inspired by the Holy Spirit.
Luke 8:21 But He answered and said to them, "My mother and My brothers are these who hear the word of God and do it."
2 Timothy 3:16 All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness
Word of God when spoken with utterances given by the Holy Spirit is more authentic and authoritative compared to the Scripture that may depend on the person penning it, and also it may get altered in translation, in copying, etc.
Furthermore, word of God will accomplish its purpose and will not go as a waste.
It is extremely important to understand the subtle and profound differences between the two to understand the ways of God for our spiritual growth.
