He will always take care of you, dear Christian caregiver. He will also always take care of your loved one for whom you are caring. God may choose to heal your loved on this earth. God, on the other hand, may at some future date decide to take your loved one home to heaven, as He took my dear husband home to heaven on January 2, 2011. Either way He is with you caring for your needs, and He is caring for the needs of your loved one.
Your future and the future of your loved one, dear caregiver, is in His hands; if you both have accepted Him as your Lord and Savior. He releases that future to you day by day and moment by moment. The Bible tells us not to worry about our tomorrows. (Check out Matthew 6:34 in the Bible.) He promise that He will never leave or forsake us. (Now check out Hebrews 13:5b.)
The difficulties and stresses of care-giving are overwhelming at times, but the Lord may be using your experiences to train you to focus on the present and not the future. He may be using your experiences to train you to focus on His Presence in your life.
