The Spirit enlightens our minds and keeps us in the line of our duty
If we have that Spirit dwelling with us—if it abides with us continually, enlightening our minds by day and by night, we are in the safe path; and when we have finished the work of the day, we reflect upon it and are satisfied with it, feeling that it is approbated of the Lord. It is our privilege to live in this way, that all our time may be spent so that we have a conscience void of offense towards both God and man. When we reflect on the day that is past and see wherein we have done evil, we should labour to improve and to advance in the things of the kingdom of God. I feel that in order for us to prize the gifts of God, the blessings of the Gospel, the privilege that we have of building tabernacles, and of living here in peace, and kneeling down in our family circles in peace, having in our society the Prophets of God, men filled with wisdom, who are capable of leading us to salvation, and of leading us into the paths of life, who do teach us the principles of truth, which will lead us back to our Father and our God,—I say, when we consider these things we ought to prize our privileges as Saints of the Most High. Brethren, we must invariably have the Spirit of God with us, that we may ever be kept in the line of our duty.
