Protestants, doesn’t John 5:29 indicate that you have to do good to have eternal life?

"You reap what you sow" is a theme which runs throughout the Bible.  The parable of the sower in Matthew 13 is a prime example. 2 Chr. 7:14 sheds light on the idea.  Jesus taught that faith is a "work", John 6:29.  Compare Eph. 2:10 and James 2:24, 26.

Given the immediate context, and given the overall emphasis on believing in John’s Gospel, I take “the good” and “the evil” as either believing or disbelieving in Him for eternal life. If you believe, you’ve done “the good.” If you have not believed, you’re disobeying God and have done “the evil.”

The Bible teaches that we are all sinners who deserve eternal separation from God in hell. But the good news is that the Lord Jesus Christ died on the cross to pay for all our sins and rose again (1 Cor. 15:3-4). Because of the shed blood of Christ, no one has to go to hell. All one must do to receive eternal life is to believe in Jesus Christ for that free gift! The moment you believe in Christ alone to save you (apart from works), you are kept eternally secure and will go to heaven when you die no matter what.

"Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life" (John 5:24).

Christians are justified by faith and a saving faith. A saving faith would result in good works. God will still examine our works to discern if our faith is genuine.

God does not need our good works, but our neighbors do. Faith leads to actions. Even our best works are tainted with selfish motives, so God will forgive a true and saving faith person.

i think your actions count

With regard to the earthly resurrection, Jesus said that those who did good things come out to a resurrection of life, those who practiced vile things to a resurrection of judgment.

 Here life and judgment contrast with each other, showing that those resurrected ones who practiced vile things after being instructed in the inspired Scriptures and scrolls are judged to be unworthy of life.

 Their names will not be written in the scroll, or book, of life. John 5:29 This would also be true of any who previously followed a faithful course but who, for some reason, turn aside during the Thousand Year Reign.

 Names can be erased.  On the other hand, those who obediently follow the things written in the scrolls will keep their names on the written record, the scroll of life, and continue living. For them, the resurrection will have proved to be one of life.

Your actions count, but they DO NOT and NEVER WILL earn you eternal life.

Salvation by faith alone has never been a legitimate theological concept. Only a political one. Fact is, salvation is by Jesus alone, according to his grace. Otherwise, Jesus could have saved himself a lot of time and trouble and simply stayed in heaven.

Matthew 5:16 
Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
