Called to be saints. What does that mean?
A saint is someone consacrated to a holy life. Therefore, those called to be saints are called to be holy.
Our sanctification is God's object in all His dealing with us. He has chosen us from eternity that we might be holy. ... As Christians we have pledged ourselves to fulfil the responsibilities resting on us, and to show to the world that we have a close connection with God. ...
God expects of us perfect obedience to His law. This law is the echo of His voice, saying to us, Holier, yea holier still. Desire after the fullness of the grace of Christ, yea, long--hunger and thirst--after righteousness. The promise is, "Ye shall be filled." Let your heart be filled with a longing for this righteousness. ... God has plainly stated that He expects us to be perfect, and because He expects this, He has made provision for us to be partakers of the divine nature. Only thus can we gain success in striving for eternal life. The power is given by Christ. ...
God's people are to reflect to the world the bright rays of His glory. But in order for them to do this, they must stand where these rays can fall on them. They must cooperate with God. The heart must be cleansed of all that leads to wrong. The Word of God must be read and studied with an earnest desire to gain from it spiritual power. The bread of heaven must be eaten and assimilated, becoming part of the life. Thus we gain eternal life. Thus is answered the prayer of Christ, "Sanctify them through thy truth: thy word is truth." John 17:17.
"This is the will of God, even your sanctification." Is it your will that your desires and inclinations shall be brought into harmony with the divine mind? {OHC 213.2-7}
Isn't this beautiful? A longing to be holier and holier should characterize our lives.
God has from eternity chosen men to be holy. "This is the will of God concerning you, even your sanctification." The echo of His voice comes to us, ever saying, "Holier, holier still." And ever our answer is to be, "Yes, Lord, holier still."
No man receives holiness as a birthright, or as a gift from any other human being. Holiness is the gift of God through Christ. Those who receive the Saviour become sons of God. They are His spiritual children, born again, renewed in righteousness and true holiness. Their minds are changed. With clearer vision they behold eternal realities. They are adopted into God's family, and they become conformed to His likeness, changed by His Spirit from glory to glory. From cherishing supreme love for self, they come to cherish supreme love for God and for Christ. {ST, December 17, 1902 par. 1, 2}
