God designed us to be sieved, His blessings flowing through us into the lives of others. This happens only when our primary focus is knowing Jesus Christ and making Him known. When we lose sight of this objective we first become root-bound then root rotten. Evidence of rot? Spiritual apathy (particularly toward spiritually lost people) and loss of joy.
Joy and happiness are not the same! “Happiness” comes from the word happenings and is emotions based on circumstances. Happiness therefore is superficial and temporary because circumstances change: Jobs end, health changes, new cars wear out, people disappoint us. Happiness, like joy, is a gift from God. We simply need to know the difference.
