What if something happens? you ask. Worrying about it isn't going to help. When you have utmost trust in your Heavenly Father, you know that whatever does or does not happen, He's watching over you and your family.
Yet, trust cannot be learned in a book or even through you reading this. The truth of it settles in your heart and mind because it is truth if you believe in God. We're wired for certain things to make the "connection". Sorta like when I plugged my camera in my laptop port and ... success! Our hearts and minds are like that laptop port and when a word like "God's truth" gets plugged in, we connect.
Sometimes the connection may take some time to be fully realized in it's fullness. Like my pictures took more time to load on the laptop than the desktop. The process of trusting is acquired through your daily life. You may not realize it, but all of the details of your life,(yup, the toddler with the fever and the flat tire and the bounced check) are worked out somehow for your good. God sees the inconveniences and the mistakes we make and is so loving that He works it out for our good.
Trusting is one of those things. As our earthly relationships take time so will our relationship with God. As you go through the difficulties and challenges of life, you will soon find you are trusting God as you see Him work all the hard stuff out. And the best trust comes when you've blown it...and it was bad...and God comes along and makes it right for you. That is when you realize how much He loves you.
Worry consumes. Even when you are not aware of it, its program is always running in the background. When worry lessens you live happier. You are not weighed down with the "what ifs". Because you have settled it that whatever happens or does not happen in your life - you will trust God.
Trust in the LORD with all your heart
And do not lean on your own understanding.
In all your ways acknowledge Him,
And He will direct your paths.
