The opportunities that come to us are offered to us by God. We should use the time that we have judiciously to do good. Our purpose in this world is to do good. We should live our lives in all our days in doing what is good. The will of God for our lives is for us to do good to everyone. What God wants us to do is good work. So, whenever you have an opportunity, do what is good.
Ephesians 2:10 (KJV) For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
Galatians 6:9-10 (KJV) And let us not be weary in well doing: for in due season we shall reap, if we faint not.
As we have therefore opportunity, let us do good unto all men, especially unto them who are of the household of faith.
There is no other time that we will have which will be a better opportunity than the ones that God is giving to us everyday. As we live our lives daily, we should consider our interactions with the brethren and other people. We should not be careless. We should have the mindset of doing that which is good and profitable to humanity. We are under obligation to serve others. Our Lord Jesus Christ came into the world to serve. We cannot do any other things than the same things which he did. We should always be prepared in our minds to serve others.
