We should never undermine with the will of God. The manner in which our future would look like it's dependent on our obedience or disobedience to the Will of God. A number of tragedies we sometimes face in life could have been averted only of we stuck to the Word of God instead doing our own thing or what other people suggested to us.
In everything relating to our lives God has in mind how he wants use to go about it. Whether it is our marriage, education, career, and so on. God is interested in every area of our lives and only He can tell us the right path that if we should go we won't end up regretting it.
Our Christianity should be questioned if we refuse to obey the will of God.
John 14:15 KJV
If ye love me, keep my commandments
Our love God is beyond mere words. It is something we should show. And one of the ways we practicalize it, according to the passage above, is by keeping every of God’s commandments. When we do this we prove that our love for God is genuine.
