We can choose the path ourselves. The Kingdom is prepared already and it is for those who are ready and faithful to Him and waiting for Him. He knows what will happen and He is always there. But ultimately, we are still the ones to make the decision to believe in Him and to do His will. If we reject Him, how can He have us by His side in heaven?
We must be purified before He brings us to His kingdom. Unless we are pure-hearted, we cannot see His kingdom. However, the devil is always there, and sin and temptation are always in our hearts to draw us away from Him. We can be pure-hearted by being obedient, having Him first in our hearts and believing in Him. Through prayer and following His word, we will communicate with Him and be closer to him. The Bible is there to help us as sometimes He will communicate to us through His word.
If He isn't perfect, who will be? He is the Creator and most powerful.
