I felt so inadequate for the task of being my husband's caregiver. It was not a role I would have chosen, and I certainly felt unprepared for that role. However, God, delights to use unlikely ordinary, weak people to do His will. When you yield your limitations and even failures to the Lord, dear caregiver, you become a wonderful instrument in the Lord's hand. His strength and not your own will then fill you.
Also, I know of no greater work in the kingdom of heaven than family care-giving. It is often a thankless job accompanied by grief and perhaps tears as one sees one's loved one's health deteriorate. It is never a pointless role, however. For whatever is done for others is done for the Lord, and it will produce a harvest of blessings and joy in God's perfect timetable.
The family care-giving role is a role that often feels as if it is leading down blind alleys. Christian caregivers, however, can be assured that their Good Shepherd is leading and guiding them each step of the way. Depend on Him for guidance and protection just as lambs follow their shepherd. As your Good Shepherd, He will walk before you and lead you. He is your hope for today, as you face your care-giving challenges. He is also your hope and the hope of your loved one for the future! He is your treasure and Strength, dear caregiver.
