Jehovah uses his holy spirit to make it absolutely clear to all who are anointed Christians that he has chosen them. In this way, the holy spirit is “a token [a pledge or promise]” given to assure them that in the future they will live forever in heaven and not on earth. (2 Cor. 1:21, 22) If a Christian is anointed, will he automatically receive his heavenly reward? No. He is sure that he has been chosen to go to heaven. However, he must remember this admonition: “Brothers, be all the more diligent to make your calling and choosing sure for yourselves, for if you keep on doing these things, you will by no means ever fail.” (2 Pet. 1:10) So even though an anointed Christian has been called to go to heaven, he will get his reward only if he remains faithful.​—Phil. 3:12-14; Heb. 3:1; Rev. 2:10. w20.01 21-22 ¶5-6
