Is it possible to stay in constant contact with God?

Ephesians 6:18 in the NLT says "Be persistent in your prayers"

Over the years I have spoken with so many believers who find it difficult to "stay in touch" with God. And when they do, they're not sure if it's genuine, authentic and real. Andrew Murray wrote: “Many Christians look upon it as a burden and a duty and a difficulty to get alone with God! That is the great hindrance to our Christian life everywhere.” God says, “Call to Me, and I will answer you, and show you great…things, which you do not know” (Jer 33:3 NKJV). The answers you seek can be found on your knees. Jesus said, “If you abide in Me, and My words abide in you, you will ask what you desire, and it shall be done for you” (Jn 15:7 NKJV). Prayer is like a platinum card; it gives you access to God’s wisdom and resources. Paul writes: “Continue steadfastly in prayer” (Ro 12:12 NKJV). The story’s told of a soldier in World War II who was caught creeping back into his quarters from some nearby woods. Brought before his commanding officer and charged with communicating with the enemy, he said he had just gone out to pray. His commanding officer asked, “Do you make a habit of spending hours alone in prayer?” “Yes, sir,” he replied. “Then get down on your knees and pray now,” roared the officer, “for you’ve never needed it more!” The soldier kneeled down and prayed so powerfully that his CO shouted, “Enough, you may go, I believe you! If you hadn’t been so often at drill, you wouldn’t have done so well at review.” Prayer isn’t like a spare tire; you can’t just leave it in your trunk and expect it to be effective when you need it. You must “be persistent in your prayers.” In other words, stay in constant contact with God.
