Jesus is the beginning and the ending of all. When He told us that in the book of Revelation, He wasn't just giving us some information about Himself. He was giving us a powerful truth we can apply today!
Let me show you how. He said He is the beginning. So no matter what challenge or situation you may be facing right now, you need to start with Him. John 1:1 says Jesus is the Word [AMP]. That means, if you're going to start with Jesus, you have to start with the Word. Don'/t do anything until you find out what the Bible has to say about your situation.
Then, continue to stand on the World. As Colossians 1:23 says, "Continue strong and sure in your faith. You must not be moved away from the hope that Good News gave you".
Continue to faith. Everything Satan does, every challenge he brings you, is intended to make you throw away God's promises and doubt His Word. So don't let go of them, no matter what may happen. Settle it with God in prayer and hold on to those promises forever.
