Romans 12:2 (NKJV)
People spend a lot of time and money trying to look a certain way. Some people go to a health club to get into shape or to maintain a certain level of fitness. There are some people who have surgery to alter how they look to maybe impress other people or to change what they see in themselves as something that is less than desirable. Some people will watch what they eat because they know that certain types of food have so many calories or this or that health benefit. But what is even more important than the physical shape we are in is the shape our life takes based on what influences us.
There are many good things in the world but we cannot allow ourselves to just follow whatever society values because those values may contradict God's values. God wants us to follow the pattern for life that He has given us in the Bible. If we fill our life, our mind, and our words with what God has said we will be "transformed". The word "transformed" here in Romans 12:2 comes from a Greek word where we get our English word "metamorphosis". Our life can be transformed as we focus on God and His Word, we can be changed and take on an entirely different shape than we have ever had before.
So, what shape are we in today? Are we thinking, acting, and talking like the world or are we thinking, acting, and talking like God? Whatever we are allowing to influence us is going to have an effect on us and cause us to be shaped in a certain way. If we find that a lot of the things in our life are there due to a wrong kind of influence and the shape we are in is more like the world than God, then we need to make a change. Check up on yourself and see what shape you are in and make sure that the pattern you are following is from God.
