I think it is essential to know God's will for your life...to know what He has called you to do and how He has called you to live your particular life. Of course, you won't know the whole of it, but you will sense what He is calling you to do right now as an individual and as a family.
Knowing is not enough, however, it is important to stay that path regardless of outside influences that pull you in other directions. The tricky part is that those influences may be from godly sources or have great ideas, but if they are not in-line with what God has called you to do, you won't find peace or blessing, only stress and discord.
It is a struggle to stay right on the path of life that God has called you to walk. Daily the world, or other Christians, will suggest alternate paths, question your choices with well-meaning intent, or opportunities will present themselves that seem too good to pass up. But it doesn't matter what anyone else thinks, all that matters is doing what is right for you and your family according to God's plan.
It is so easy to get side-tracked, or feel pressured by what others are doing. Even Christians, or those with similar callings, can be detractors. Not on purpose, of course, but they have a different agenda than yours (no ones is exactly the same), so listen to their ideas, then assess if it is inline with how God is calling you to live.
Likewise, don't succomb to Satan's lies that you are not doing enough or are living an off-beat life just to be different. We are called to be different from the world, but more importantly, we are called to live the life God called us to live...whatever that may look like.
It is equally easy to get so caught up in the world's current that we don't take the time to quiet ourselves, seek out God, and find out what His will is for our lives at this time, and then obediently and bravely follow His leading.
So find God's will for you and stay true to living the life He called you to live. Live the life, walk the walk, that God wants for you each day, whether in word and action, attitude or choices. Stay true regardless of pressure and then you will find peace.
It is so important to know God's plan for your life and to know the route he has called you to journey on, even if it is different from everyone else. It takes courage, insight, and conviction to stay the path that wavers from what others are doing.
