1 Timothy 6:
1 Timothy 6:12 (NIV)
“Fight the good fight of the faith. Take hold of the eternal life to which you were called when you made your good confession in the presence of many witnesses.”
Faith is key. For those of us who are believers, it is important that we witness to non-believers what God has done for us. He died for us on the cross, so that all sin is forgiven, and that we would have everlasting life.
