The term “sacrifice” has acquired a negative connotation, but for the Christian it indicates the joy of participating in the life of the Lord. Paul speaks of sacrifice and joy in the same phrase. The two belong together, Phil 2.17.
The decline of joy as a spiritual possession today in contrast with primitive Christianity is due to some imperfection in the Christian life. —Carl Henry
No one and nothing can rob you of your joy unless you choose to drop that joy and pick up offense, resentment, or bitterness in its place. —Katherine Walden
Singing is not to produce our joy, but to express it. “Is anyone among you suffering? He should pray. Is anyone in good spirits? He should sing praises” Jas 5.13. The emotion produced by music will quickly pass.
It is all about you. Not what you want, but what is best for you. Not what you think will make you happy, but what will give you lasting joy. God wants to show you the difference. But first you have to let go of yours to find yourself, in Him.
