If we find it hard to obey God, then we are not submitted to Him. It is not hard to obey God when we have His mind, we will desire His will.
Those who are working real hard to obey Christ, without the desire, have not trusted Christ, perhaps for salvation but nothing more than that.
When we love Christ we have a drivenness to know His Mind. When we have His mind, we want to obey.
1 Corinthians 2:16 "…15 The spiritual man judges all things, but he himself is not subject to anyone’s judgment. 16 “For who has known the mind of the Lord, so as to instruct Him?” But we have the mind of Christ."
