Love is faithful or, in other words, “full of faith” in the One who loves. If there is not faithfulness then there is not love. Eve was not faithful to the Lord when she ate the fruit. She no longer loved God.
When the woman saw that the tree was good for food, and that it was a delight to the eyes, and that the tree was desirable to make one wise, she took from its fruit and ate; Genesis 3:6a
Faithfulness is what the Lord looks for in those who serve Him because He knows that if they are not faithful then they do not love Him. If love is not your motive then whatever you do is going to be for selfish reasons even though it may “look” good to others. If you love God then you will love others. If you are faithful to God then you will be faithful to those to whom you are committed.
His master said to him, ‘Well done, good and faithful slave. You were faithful with a few things, I will put you in charge of many things; enter into the joy of your master.’ Matthew 25:23
Someone may well say that it does not matter what they do because God is going to do what He wants to do regardless. The Lord certainly can and does do what He wants to do but those who have that attitude are not faithful. Faithful means that we are full of faith and believe what He says and we do what He commands. Faith is what pleases the Lord and when we believe Him in faith and act on what He says it brings Him delight.
And without faith it is impossible to please Him, for he who comes to God must believe that He is and He is a rewarder of those who seek Him. Hebrews 11:6
Eve sinned because she did not act in faith on what the Lord had said and commanded them. She began reasoning in her heart about what was best for her rather than trusting what God had said.
and whatever is not from faith is sin. Romans 14:23b
The outcome of Eve not having faith and believing what God said was that she disobeyed God. She did what she wanted, what seemed good to her and what was delightful. It really did not matter what benefits the fruit had to offer because the Lord said not to do it. When you start reasoning in your heart then you have already started down the path of sinning.
There is no wisdom and no understanding
And no counsel against the Lord. Proverbs 21:30
Eve exchanged the truth of God for a lie and the outcome was sin. Every time we sin we also have exchanged the truth of God for a lie. We have believed the lies of the devil rather than the truth of God. The devil uses only one weapon to get us to sin and that is lies. Often we are deceived and do not realize it until it is too late and our resulting sin brings us death to our soul, in the form of grief, sorrow, guilt, regret and much pain. It also brings consequences in relationships and marriages. We were deceived and sinned because we listened to the lies of the devil rather than to the Lord.
He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he speaks a lie, he speaks from his own nature, for he is a liar and the father of lies. John 8:44
The only way that we will ever have the life that the Lord designed for us and the loving marriage and relationships that He intended is if we know God’s Word and if we are faithful to Him by believing what He says and obeying it.
And to whom did He swear that they would not enter His rest, but to those who were disobedient? So we see that they were not able to enter because of unbelief. Hebrews 3:18,19
Faith and obedience go together. You can not have one without the other. The Lord has a rest for us and it is heaven. Those who have believed and their faith is a living faith expressed through obedience will enter into heaven because they have believed on the One and Only Son of God, Jesus Christ.
