Praying for someone's salvation. Is there a point? According to I Timothy 2:4 (NIV), God "...wants all people to be saved and to come to a knowledge of the truth".

But since we have free will, God cannot make us choose to accept the salvation that is available through his Son.

Since I believe that God loves others more than I can, and he desires them to be saved. I think it's logical to conclude that he's going to do everything He can to draw them to Him.

So then what is the point of praying for someone's salvation?
Even if we can't pray away someone else's free will or convince God to bend the rules regarding the requirements of salvation, there can still be merit in praying on behalf of others with a slightly different attitude.  Perhaps "let them have experiences that will lead them to the truth," or "let their hearts be softened, that they may give heed to the Holy Spirit and accept the truth when it is presented to them" would be more appropriate.

And, as JustinY pointed out in his comment, praying for the welfare of others can be beneficial to us.  Simply because we pray to God for something to happen doesn't mean we can't directly take part in bringing such a prayer to fruition.  If we seek to truly pray in Jesus's name and harmonize our will with his, it will lead us to be more conscious of the spiritual needs of others in our day-to-day lives, and to find effective ways to bring others to Christ.
