When we come to Christ, the barriers between us and God are broken down, and God Himself comes to live within us by His Holy Spirit. In other words, we now know God -- and He knows us. Think of it: We now have a personal relationship with the God of the universe!
But like any other relationship, it needs to be nurtured and strengthened. If it isn't, it will wither and grow cold; God will seem distant to us, and we will no longer think of Him as our friend. We may even drift into ways of living that don't honor Him, and instead may lead us to destruction. The Bible warns, "Do not love the world or anything in the world.... The world and its desires pass away" (1 John 2:15,17).
How do we learn to walk with God every day? Think of a human friendship: How do we grow closer to someone on a human level? The most important way is by spending time with them -- talking with them, listening to them, sharing your concerns with each other, and even helping them when they need our help.
And the same is true with God. When we read or hear His Word, the Bible, He speaks to us. When we pray, we speak to him. And when we worship Him and obey Him, we are doing His will and participating in His work. Make sure of your commitment to Jesus Christ -- and then discipline yourself to walk with Him every day of your life.
