Nothing in life is more important than your relationship with God. Nothing. And not just because you need to confirm where you go when you die. Salvation begins when we ask Jesus into our hearts. Our life begins then, not later.
How do we know this? Because Jesus taught us to pray, on earth as it is in heaven. That means that your life now should reflect heaven. How will that happen if God is not your number one priority?
God must be first. Jesus said to him, You shall love the Lord your God with all your heart, with all your soul, and with all your mind. (Mat 22:37) This is not a suggestion. This is a command from God and always has been.
And when we do line up our priorities with our focus on God, He promises to bless us and take are of all. But seek first the kingdom of God and His righteousness, and all these things shall be added to you. (Mat 6:33) ALL these things to be added to you are all the things you need for your life. It’s a promise, and God cannot lie. When your focus is right, everything in your life is blessed. You just need to be honest about where you focus is.
