Sure, no problem.
When God respects human freedom, that means God let them continue sinning against Him.
Then you might say, oh, I chose to become a Christian, I choose to do charity, I choose to comfort my close ones, all these good things, how can they be sin?
From man's point of view, yes, you actively used your freedom to choose. However, in the fullness of the event, you were not able to choose this if God has not at some point "fixed" you. For we have no freedom of such eversince they are corrupted when Adam fell, until Christ dwell in us, giving us a renewed life, thus obtaining such freedom.
Then you might say, well, what about non-believers, buddhists, muslims, many of them do good, charity, but they don't believe in Christ. Then you see, when they have achieved their charity, they will not glorify God, they will not give praise to the one true God, hence, for all have sinned and fall short of the glory of God. The motive was already of selfish intention. Nevertheless, by these deeds, they could gain God's acceptance, while salvation is still yet a second phase, so that they will know, all praise is left for God, not for themselves.
The Truth shall set you Free. And Christ is the Truth.
