神要我們活得充滿喜樂，所以保羅說要常常喜樂。在舊約的書卷中，到處都可以看到神應許人快樂的話。然而，聖經對喜樂有不同的看法，因此也要求我們以不同的方法去追求快樂。
我們可以用一個快樂階梯來說明基督徒追求快樂的方法，同時也顯出我們對快樂的深刻認識。基督徒也是人，也有物質的需要，所以我們也追求物質的豐富，但同時也認識到物質的豐富不必然帶來心靈的快樂。其實，在我們日常生活中，曾經看見過有人賺了許多錢但不快樂，也看過有人事業很成功卻也不快樂，我們也看過有人交友滿天下也不快樂。
聖經已告訴我們快樂的源頭在神裡面。保羅直接告訴我們，在主裡是喜樂的泉源：「你們要因為與主連結而常常喜樂。我再說，你們要喜樂。」（腓4:4）我們可以從聖經中找到喜樂的階梯，知道喜樂的源頭，和喜樂最高的境界，而這一切都在乎我們與主的關係。
God wants us to live happily. This is the reason why Paul tells us to be joyful always. We can find in the Old Testament books full of God’s promises of giving happiness to His people. In Bible, however, happiness has its unique definition, and therefore, God also requires us to acquire happiness in a unique way.
We can use a pyramid to illustrate how Christians should pursuit happiness, and reveal our profound understanding in this issue. Christians are also human beings, so we have physical needs. We will pursuit earthly wealth, even though we understand that material goods won’t necessary quarantine happiness, especially spiritual joy. As matter of fact, we see rich people and professionally successful people are unhappy in their lives. Sometimes, we also see people are unhappy even though they have a lot of friends.
Bible tells us that the ultimate source of happiness is in the Lord. Paul tells us with no hesitation that we will have joy in the union with Christ, “May you always be joyful in your union with the Lord. I say it again: rejoice!” (Phil 4:4) We can find the ladder to happiness in the Bible, and know that the ultimate source of joy and its highest contentment is in the relationship with the Lord.
