II Corinthians (KJV)

12:9 And he said unto me, My grace is sufficient for thee: for my strength is made perfect in
     weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ
     may rest upon me. 
 

How is God's grace manifested toward us?

John (KJV)
3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth
     in him should not perish, but have everlasting life.

What blessings has God given his children?

Ephesians (KJV)
1:7 In whom we have redemption through his blood, the forgiveness of sins, according to the
     riches of his grace; 
1:8 Wherein he hath abounded toward us in all wisdom and prudence; 
1:9 Having made known unto us the mystery of his will, according to his good pleasure which
     he hath purposed in himself: 
1:10 That in the dispensation of the fulness of times he might gather together in one all things in
     Christ, both which are in heaven, and which are on earth; even in him: 
1:11 In whom also we have obtained an inheritance, being predestinated according to the
     purpose of him who worketh all things after the counsel of his own will: 
1:12 That we should be to the praise of his glory, who first trusted in Christ. 
1:13 In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation:
     in whom also after that ye believed, ye were sealed with that holy Spirit of promise, 
1:14 Which is the earnest of our inheritance until the redemption of the purchased possession,
     unto the praise of his glory. 
1:15 Wherefore I also, after I heard of your faith in the Lord Jesus, and love unto all the saints, 
1:16 Cease not to give thanks for you, making mention of you in my prayers; 
1:17 That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of
     wisdom and revelation in the knowledge of him: 
1:18 The eyes of your understanding being enlightened; that ye may know what is the hope of his
     calling, and what the riches of the glory of his inheritance in the saints, 
1:19 And what is the exceeding greatness of his power to us-ward who believe, according to the
     working of his mighty power, 
1:20 Which he wrought in Christ, when he raised him from the dead, and set him at his own right
     hand in the heavenly places, 
1:21 Far above all principality, and power, and might, and dominion, and every name that is
     named, not only in this world, but also in that which is to come: 
1:22 And hath put all things under his feet, and gave him to be the head over all things to the
     church, 
1:23 Which is his body, the fulness of him that filleth all in all. 

To whom is the grace of God promised?

Psalms (KJV)
84:11 For the LORD God is a sun and shield: the LORD will give grace and glory: no good thing
     will he withhold from them that walk uprightly. 

Does God's grace work?

Romans (KJV)

8:38 For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers,
     nor things present, nor things to come, 
8:39 Nor height, nor depth, nor any other creature, shall be able to separate us from the love of
     God, which is in Christ Jesus our Lord. 

Should we seek God's grace?

Hebrews (KJV)
4:16 Let us therefore come boldly unto the throne of grace,
that we may obtain mercy, and find grace to help in time of need.
