Every christian, whether single or married; whether old or young, should live their lives to please God. The Bible says that we should mind the things that are from above since we have been raised with Christ. It says that anyone who minds earthly things is dead already. We are to be mindful of how we can please God no matter what state we are in.
To please God, we need to be vested with the knowledge of the things of God. We should fear God and keep His commandments. We should trust Him and depend on Him. Our whole heart should delight in pleasing God and that alone. The love of God should be paramount in our hearts.
Also, we should seek to serve other people. This is the commandments of God. The Bible says that as much as it depends on us, we should live peaceably with all men. It also says that we should do good to all men. So, to please God we must ensure that we maintain a peaceful co-existence among others. We should always seek to do good to all men.
