Remember!

"Remember that Jesus Christ, of the seed of David, was raised from the dead according to my gospel" (II Timothy 2:8 NKJV )
The redemptive work of Christ  is done and accomplished once but it has a continous effect till eternity. Healing and health, prosperity, sanctification, all round victory, justification, righteousness, peace and joy in the Holy Ghost, are few of the gracious benefits of redemption; they are free gifts of grace which are paid for by the blood of Christ.
"being justified freely by His grace through the redemption that is in Christ Jesus," Romans 3:24 NKJV.
As sure as the benefits are, a believer might not be enjoying them except he makes conscious effort to always remember what Christ has done to procure these benefits.
The believer must establish and maintain a sound reminder system that will keep the work of Christ bright in his memmory.
If you notice a "fading" benefit in your life, it is nnot becuase God withdraws it, "For the gifts and the calling of God are  irrevocable. "  Romans 11:29 NKJV; It might just be that your heart has lost touch with the work of Christ as recorded in His word.
I beseech you to latch on to God's word and let your heart be stirred up to remember what Christ has done for you.
