The longest discussion of the practical outworking of the Spirit in the ministry of the local church is found in 1 Corinthians 12-14. Consider that more than two-thirds of that material confronts the necessity of unity and love and compares the congregation of believers to a body with all its' individual parts. With such emphasis placed more on love and unity than manifestations of the Spirit, you begin to understand how the Psalmist would acknowledge that only when brothers dwell together in unity can God command His blessing.
