Music holds a significant place in worship and spiritual expression, as seen in its power to transform and unify. By singing hymns together during church services, we are unified in harmony as the body of Christ before God, facilitating oneness of mind. For the duration of the hymns, we can be in harmony, mentally and vocally, with our brethren. Once the hymns end and the service concludes, we must maintain that unity, continuing to express the joy and godly praise of the Psalms in our everyday lives.

One of the major commands that God gives both spiritual and physical Israel is to not forget Him or His laws as we progress in our lives during work, relations with friends and family, and within the church. In Deuteronomy 8 the law to remember God is emphasized during times of greater prosperity as good times can cause us to focus on the blessings instead of the Giver. Reviewing the concept of forgetting and the mechanisms by which it happens we see that there are several ways that our neglect of keeping God in our memory can occur. Psychologist Kendra Cherry lists four important points: "forgetting by decay, forgetting by interference, forgetting by failure to store, and motivated forgetting." God's called out ones are often afflicted severely with "spiritual Alzheimer's." Israelites forgot God after seeing powerful miracles. Both ancient and modern Israelites under the New Covenant must by constant vigilance remember God and engage in activities such as prayer, Bible Study, and singing to reinforce our memory that we are dependent upon God's grace and mercy.
