You have been born of the Spirit, and Jesus said in His Word that the Kingdom of Heaven is within you.  Therefore, it should be a priority with you to seek the realities of the Kingdom in your day to day life on earth.  No more should you faint nor become weary or frustrated because things are happening to you or around you.  No more should your needs overwhelm you.  Stepping up simply means using your faith to enter the presence of God. It's simply a decision to become Kingdom conscious.
