I will bless the Lord at all times: his praise shall continually be in my mouth. Psalm 34:1.
(WGD 213.1)
Shall all our devotional exercises consist in asking and receiving? Shall we be always thinking of our wants, and never of the benefits we receive? Shall we be recipients of His mercies, and never express our gratitude to God, never praise Him for what He has done for us? We do not pray any too much, but we are too sparing of giving thanks. If the lovingkindness of God called forth more thanksgiving and praise, we would have far more power in prayer. We would abound more and more in the love of God, and have more bestowed to praise Him for. You who complain that God does not hear your prayers, change the present order, and mingle praise with your petitions. When you consider His goodness and mercies, you will find that He will consider your wants.
(WGD 213.2)
Pray, pray earnestly and without ceasing, but do not forget to praise. It becomes every child of God to vindicate His character. You can magnify the Lord; you can show the power of sustaining grace. There are multitudes who do not appreciate the great love of God nor the divine compassion of Jesus. Thousands even regard with disdain the matchless grace shown in the plan of redemption. All who are partakers of this great salvation are not clear in this matter. They do not cultivate grateful hearts.
(WGD 213.3)
But the theme of redemption is one that the angels desire to look into; it will be the science and the song of the ransomed throughout the ceaseless ages of eternity. Is it not worthy of careful thought and study now? Should we not praise God with heart and soul and voice for His “wonderful works to the children of men”?—Testimonies for the Church 5:317.
