There is no guaranteed way through which we can receive God's blessings. There are principles that guide us through life but there is no such thing as a cause and effect pattern that will guarantee blessing.
We can work hard at raising great children or building a great marriage. We can work diligently at a business or making lasting friendships. Ultimately though, we do not have that much control over the outcome and may not achieve our desired result.
Christian leaders can work hard and serve God faithfully. Some enjoy God's blessing by building a substantial ministry but others do not.
Some parents parent faithfully and produce fantastic children but other parents whom have been just as faithful, do not.
Ultimately if we live with a cause and effect mindset regarding the blessing of God, life becomes a roller coaster and disappointing.
If children, marriage, business or friendships succeed, we are happy. If one fails, though, we experience contempt not just for self but for others.
If we live with a cause and effect mentality, or as one whom expects blessing for good works, life and God are disappointing. We live, preoccupied with using God as a source of reward, rather than aiming at a relationship with Him.
Beyond the splendor that life has to offer, focusing on the thought that God Himself is the ultimate blessing is fulfilling. He is the constant relationship that lifts us despite trials and loves and accepts us in spite of success or failure.
