Accepting the free gift of salvation was never meant to be a lifetime sentence of fearing failure and overwhelming guilt. Walking lockstep with God simply means that we lean on Him as the source of our joy and strength.
Whatever trial you are facing today, know that God has a purpose for your pain beyond your understanding. Know that He holds your broken heart in the palm of His hand. Let Him use your trial to refine you and minister to others. Better days are ahead, if not here, most assuredly in Heaven where all crying, sorrow, and pain will be gone (Rev. 21:4).
