You can't trick God. He knows all of our thoughts and deeds. We can't sidestep the reality that we have sinned against God. None of us are perfect. Yet, only perfect people deserve to go to Heaven. So, the only way that we can be forgiven, is if we're sincere, and are honest with God, about our sin. As the above scripture shows, he's willing to forgive us. It's the powerful nature of his infinite grace. However, we have to be honest about our sin, and ask him to forgive us.
The second thing a person has to do, is accept Christ as Lord, and recognize that there is no one else who can save us.
Here's what we read in Romans 10:8-13:
What it says is this: "God's message is near you, on your lips and in your heart"--that is, the message of faith that we preach. If you confess that Jesus is Lord and believe that God raised him from death, you will be saved. For it is by our faith that we are put right with God; it is by our confession that we are saved. The scripture says, "Whoever believes in him will not be disappointed." This includes everyone, because there is no difference between Jews and Gentiles; God is the same Lord of all and richly blesses all who call to him. As the scripture says, "Everyone who calls out to the Lord for help will be saved."
-Romans 10:8-13
The Bible makes it very clear that it's only through Jesus, and no one else, that we can be saved. So don't be fooled into thinking that all religions are basically the same.
Here's what we read in Acts 4:8-22:
Peter, full of the Holy Spirit, answered them, "Leaders of the people and elders: if we are being questioned today about the good deed done to the lame man and how he was healed, then you should all know, and all the people of Israel should know, that this man stands here before you completely well through the power of the name of Jesus Christ of Nazareth--whom you crucified and whom God raised from death. Jesus is the one of whom the scripture says,
'The stone that you the builders despised
turned out to be the most important of all.'
Salvation is to be found through him alone; in all the world there is no one else whom God has given who can save us."
The members of the Council were amazed to see how bold Peter and John were and to learn that they were ordinary men of no education. They realized then that they had been companions of Jesus. But there was nothing that they could say, because they saw the man who had been healed standing there with Peter and John. So they told them to leave the Council room, and then they started discussing among themselves. "What shall we do with these men?" they asked. "Everyone in Jerusalem knows that this extraordinary miracle has been performed by them, and we cannot deny it. But to keep this matter from spreading any further among the people, let us warn these men never again to speak to anyone in the name of Jesus."
So they called them back in and told them that under no condition were they to speak or to teach in the name of Jesus. But Peter and John answered them, "You yourselves judge which is right in God's sight--to obey you or to obey God. For we cannot stop speaking of what we ourselves have seen and heard." So the Council warned them even more strongly and then set them free. They saw that it was impossible to punish them, because the people were all praising God for what had happened. The man on whom this miracle of healing had been performed was over forty years old.
-Acts 4:8-22
Acts 4:12 is the key verse which points out that, it's only through Jesus, that we can be saved. However, I've provided this larger portion, so that we can all remember the extraordinary circumstances that back up the validity of Christ.
Jesus performed miracles, and so did many of his followers; in his name. The miracles are important because they're a constant reminder that everyone else, other than Jesus, is a fraud. Jesus proved his position and authority, by use of miracles. They set him apart.
