The hardest work you will have to do is believe

Romans 4:1 What shall we say then that Abraham our father, as pertaining to the flesh, hath found?
2 For if Abraham were justified by works, he hath whereof to glory; but not before God.
3 For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness.
4 Now to him that worketh is the reward not reckoned of grace, but of debt.
5 But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.
6 Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness without works,
7 Saying, Blessed are they whose iniquities are forgiven, and whose sins are covered.

Introduction:
John 6:29 Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.
30 They said therefore unto him, What sign shewest thou then, that we may see, and believe thee? what dost thou work?

I. That all things work for the good of God
Rom 8:28 And we know that all things work together for good to them that love God, to them who are the called according to his purpose.

II. That God the Father, Son and Holy Spirit created all things
Gen 1:1 In the beginning God created the heaven and the earth.
2 And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
2 The same was in the beginning with God.
3 All things were made by him; and without him was not any thing made that was made.
John 1:14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.

III. God is a God of grace, love, and forgiveness
John 3:15 That whosoever believeth in him should not perish, but have eternal life.
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.

IV. That a loving God is also a God of wrath
Mt 25:41 Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:

V. That the Bible is the very word of God
II Tim 316 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
17 That the man of God may be perfect, throughly furnished unto all good works.

V. If we love God, we will keep his commandants
John 14:15 If ye love me, keep my commandments.

What are some of His commandants?
1. Take gospel to all the world
Matt 28:18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.

2. Love one another
John 13:34 A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.
John 13:35 By this shall all men know that ye are my disciples, if ye have love one to another.
John 15:12 This is my commandment, That ye love one another, as I have loved you.
John 15:17 These things I command you, that ye love one another.
Gal 5:13 For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another.

3. Love the church and support it
Heb 10:25 Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.
