A very good text is Mathew 5:3 is: "Happy are those conscious of their spiritual need, since the kingdom of the heavens belongs to them." This scripture is important because it highlights the true venue to seek happiness which is by means of seeking to satisfy our spiritual needs. Humankind tends to try and seek happiness by means of material possessions and long successful careers, however, to their disbelief they find out later in life that the pursuit of these things does not provide happiness in the long run but rather disappointment and a sense of under achievement.
Going along with trusting in the Lord, I think this is an excellent verse for Mankind to live by:
Deut 22:28 If a man find a damsel that is a virgin, which is not betrothed, and lay hold on her, and lie with her, and they be found; 29 Then the man that lay with her shall give unto the damsel's father fifty shekels of silver, and she shall be his wife; because he hath humbled her, he may not put her away all his days.
This one of the most despicable laws the Abrahamic God laid down, So trust in the lord and he'll protect you.
