Philippians 2:14 Do all things without murmurings and disputings:
15 That ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world;
16 Holding forth the word of life; that I may rejoice in the day of Christ, that I have not run in vain, neither laboured in vain.
We see now that after we found out we are responsible for our own salvation we are not to complain or question why some things happen. When the children of Israel were freed from Egypt one of the main problems God had with them was their complaining. This raises the question why do we complain about anything since God set us free with His son Jesus. We still have a battle to fight with the world we live in today but because we are sons of God we should be able to live blameless and harmless without rebuke. If we can live the life Christ ask of us we can give what we have to others helping us to rejoice in the day Christ returns and know that our work has not been in vain. Sometimes we feel we are beating our head up against a wall and that is when we want to murmur and complain but we should be praising God for the trials He puts us through because they help to make us stronger.
