'Trying' in the Bible

For am I now making an appeal to people or [to] God? Or am I seeking to please people? If I were still trying to please people, I would not be a slave of Christ.

For you have heard about my former way of life in Judaism, that to an extraordinary degree I was persecuting the church of God, and trying to destroy it,

Are you so foolish? Having begun by the Spirit, are you now trying to be made complete by the flesh?
