Without a definite purpose or aim in our life, we can either float through life or work towards no set goal. We seek to attain eternal life, happiness, satisfaction in this current life, to bring honor to God, and blessings to our fellowmen. Grace should not remove our desire for improvement and growth.
Accepting others choices to be what they want to be, concluding that is not your choice. You would not run your life like that. Leave them to do their thing. It will often mean your prosperity, spiritual growth, health improvement, safety, and peace of mind. Everyone will reap the results of their choices.
Hosea 10:12 Sow to yourselves in righteousness, reap in mercy; break up your fallow ground: for [it is] time to seek the LORD, till he come and rain righteousness upon you.
10:13 Ye have plowed wickedness, ye have reaped iniquity; ye have eaten the fruit of lies: because thou didst trust in thy way, in the multitude of thy mighty men.
