From Shakespeare's point of view according to Sonnet 29, the significance of love is that it can bring wealth and songs and hope. The quatrain bemoans the times when fate leads to loss of wealth and loss of respect in others' opinions. The speaker claims that, at such times, he weeps alone, heaven turns a deaf ear, and he curses his fate. The sonnet topic pivots at Line 5 and the speaker tells of the things he wishes for at such a time and how he is least contented with what he has. Line 9 brings the topical pivot of the sestet in which he states that even though he almost despises himself, a thought of his beloved changes his state. In the sestet the speaker equates love to the lark at sunrise rising up to sing from an earth as downcast as he himself is (sullen); to the lark's songs of praise (hymns) sung at "heaven's gate"; to the source of such wealth that now the speaker wouldn't trade places with a king even though ten lines earlier, he wanted to trade places with everyone. In short, Shakespeare is describing the significance of love as being the source of hope and confidence and happiness.
