The definition of girding up your mind is ready to work. We won’t always understand why God is calling us to obey Him, but it is so He can do His work in our lives.
God keeps us through His Holy Spirit, His Word and His power that can control our lives. Hide God’s Word in your heart and mind so it changes how you live.
Because Christ is alive we have a certain hope for our present, future and eternity. Our faith is kept by the Word in our hearts and by the Holy Spirit living in us.
Start with God and ask Him for advice. We can invite God to get involved in our ordinary life. You get comfortable with God as Father when you make Him Lord.
