"Very early in the morning while it was still dark, Jesus got up, left the house and went off to a solitary place, where He prayed." (Mark 1:35)
This is just one example of many times in the Gospels we read of Jesus taking time to get away and spend time with His Father. It was a regular practice for Him. Jesus deemed it to be important to set aside time to talk to the Father.
It's a simple truth . . .
. . . If Jesus thought it was important to spend regular time with the Father when He walked on earth, then that's probably an indication that we should as well. If we're being transformed to be more and more in the image of God as we follow Him, then it makes sense that we make our priorities the same as the ones Jesus had when He was on earth.
I'll be the last one to tell you when you need to spend time with God. I'm also not one to tell you exactly what that time should look like. But, I will say that you need to have that time with God on a regular basis. The part about spending time with God isn't an option for those who claim to follow Him.
