Nathanael suffered from a skepticism that afflicts many people.
It is to his credit that he came to the Lord and gave Him a chance to prove who He was.
We can only speculate what it was that Jesus saw Nathanael doing under that fig tree (v. 50), but it is very clear that it was something that proved beyond a doubt that Jesus was the Christ.
Jesus didn't rebuke Nathanael for his doubts, instead he removed them. The Lord has an answer for every doubt that we have. We need to be without deceit before the Lord as Nathanael was (v. 47) and come to Him when we are plagued with doubts instead of running from Him or avoiding Him.
Jesus knows us. He remembers that we are but dust (Psalm 103:14). It is not a sin to doubt, but it becomes sin if we harbor those doubts. We should do as Nathanael did and bring our doubts to the Lord. Let's allow Him to deal with them.
