Psalms 127:1 (KJV) Except the LORD build the house, they labour in vain that build it: except the LORD keep the city, the watchman waketh but in vain.
127:Title Ps 120. This psalm was either for or by Solomon the builder of the temple – the Hebrew can mean either.
These verses do not teach laziness, idleness, or carelessness. They teach the uselessness of human effort apart from God. Of course, we must work diligently and well ( Eccl 9:10 ; 1 Cor 15:58 ). But we must recognize that it is God alone Who can prosper the work and make it truly fruitful. Though the ungodly may build huge mansions, great fortunes, and big families, it will all come to nothing, and is what Solomon called in another place “vanity of vanities”( Eccl 2:4-11 ).
Anything that we do, that is not of God, is in vain. It will bring nothing but the attention we may receive on earth – and that never amounts to anything. When you work on things of God, you are storing up heavenly treasures that will last for life.
