The strength of your focus determines the degree to which you are susceptible to distraction. Your focus determines your future.
“Let us fix our eyes on Jesus, the author and perfecter of our faith….” (Hebrews 12:2 NKJV).
“I press on toward the goal to win the prize for which God has called me heavenward in Christ Jesus.” (Philippians 3:14 NKJV).
The object of your affection determines your focus. So focus on God and the vision He has for your life.
