All your happiness, peace, joy, and success in this life are dependent upon genuine, trusting faith in God. This faith will prompt true obedience to the commandments of God. Your knowledge and faith in God is the strongest restraint from every evil practice, and the motive to all good.
Believe in Jesus as one who pardons your sins, one who wants you to be happy in the mansions He has gone to prepare for you. He wants you to live in His presence; to have eternal life and a crown of glory.—Messages to Young People, 410.
Whatever is done to the glory of God is to be done with cheerfulness, not with sadness and gloom. There is nothing gloomy in the religion of Jesus. If Christians give the impression by a mournful attitude that they have been disappointed in their Lord, they misrepresent His character, and put arguments into the mouth of His enemies. Though in words they may claim God as their Father, yet in gloom and sorrow they present to the world the aspect of orphans.
Christ desires us to make His service appear attractive, as it really is. Let the self-denials and the secret heart trials be revealed to the compassionate Saviour. Let the burdens be left at the foot of the cross, and go on your way rejoicing in His love who first loved you. Men may never know of the work going on secretly between the soul and God, but the result of the Spirit’s work upon the heart will be manifest to all; for He “that seeth in secret, shall reward thee openly.”—Thoughts from the Mount of Blessing, 88. WGD 260
Those who are engaged in service for the Master need an experience much higher, deeper, broader, than many have yet thought of having. Many who are already members of God's great family know little of what it means to behold His glory and to be changed from glory to glory. Many have a twilight perception of Christ's excellence, and their hearts thrill with joy. They long for a fuller, deeper sense of the Saviour's love. Let these cherish every desire of the soul after God. The Holy Spirit works with those who will be worked, molds those who will be molded, fashions those who will be fashioned. Give yourselves the culture of spiritual thoughts and holy communings. You have seen but the first rays of the early dawn of His glory. As you follow on to know the Lord, you will know that “the path of the righteous is as the light of dawn, that shineth more and more unto the perfect day.” Proverbs 4:18, R.V., margin. MH 503
But let all those that put their trust in thee rejoice: let them ever shout for joy, because thou defendest them: let them also that love thy name be joyful in thee. Psalm 5:11, KJV
