Questions regarding salvation

According to the Bible -

Does anyone deserve to be saved?

Is anyone actively seeking, loving or obeying God, by their own choice and power alone?

Does God's nature (love, justice, holiness, mercy, etc.), require He save or try to save anyone?

If someone never heard the gospel and perished in their sin, could they charge God with being unjust?

If some heard the gospel and were saved and others did not hear it and perished in their sin, could they charge God with being unjust?

Is God currently trying equally hard to save all people?

Has God always been trying equally hard to save all people?

Has any one person or group of people ever had an advantage regarding salvation?

Is God involved in the calling and sending of missionaries?

Does someone who has the gospel presented to them in person have an advantage over someone who does not?

If you went to heaven and another person didn't - why?

If God choose to save some people by bringing them the gospel through His word and the work of the Holy Spirit and choose to leave some people in their willful rebellion/sin and it's consequences, for His own self-glorifying reasons, could He be charged with being unjust by anyone?

If you answered no to the last question, then you are at least logically OK with the foundational truth of a reformed view of salvation! Now, you must decide if it is the Biblical teaching regarding salvation?
