In Mark 13, there are things Jesus says that speak to what the apostles would go through. There are things Jesus says that speak to what tribulation saints will go through. And there are things Jesus says that speak to what we are going through right now.
To each, Jesus gives a similar instruction—take heed. Pay attention!
Read the Bible. Talk to God—ask Him how He wants you to function in your daily responsibilities, in your workplace, and in your relationships. Talk to Him about everything.
If you have made Him the Lord of your life, you are a part of His kingdom. He loves you and wants to use you. He has radical things for you in the smallest bits of faithfulness that will ripple on into eternity that you might never know about until eternity.
Trust Him. Love Him. Serve Him. And actively wait from Him in the meantime, for Jesus is returning soon!
