There are as many different ways to share the good news about Jesus as there are people on the planet. I will be sharing some ideas over the coming weeks if you're feeling a bit stuck.
The full passage of 1 Timothy 2:1-4 says, First of all, I ask that you pray for all people. Ask God to bless them and give them what they need. And give thanks. You should pray for rulers and for all who have authority. Pray for these leaders so that we can live quiet and peaceful lives—lives full of devotion to God and respect for him. This is good and pleases God our Savior. God wants everyone to be saved and to fully understand the truth.
In this passage Paul was instructing Timothy about public prayer and was telling him that praying for the salvation of the whole world was an important part of this. I think that praying for the unsaved is an important part of your personal prayer time too. You can pray for salvation for your unsaved family and friends, for opportunities to share God's good news with unsaved people you know and ask for wisdom to know what to say.
CHALLENGE: Choose several unsaved friends or family members and pray for them daily.
The whole point of the Bible is that God loves us. 1 John 4:9 says, God showed his love for us when he sent his only Son into the world to give us life. It's easy to get distracted when sharing the good news but this verse sums it up perfectly. If that's the only message you get across, you have done a good job.
Obviously the best book to read here is the Bible but here are some other suggestions to help you to work out what you believe and why:

Jesus told us to live in a way that shines the light of the gospel - to be kind, generous, loving, joyful, peaceful, patient... People always pay more attention to what you do than what you say. I was watching a reality TV show recently where two of the contestants claimed to be Christians but they were mean, critical, judgemental and rude. Their words and actions did more to harm the faith than the help it.
CHALLENGE: Can people tell that you're a Christian by watching you? What can you do to put your faith into action?
