After knowing and believing in the existence of God, the next thing is building a relationship with God..which is a day to day process. Getting to know more about God and his wonders. In building a relationship with anyone, communication becomes the greatest key.
Communication is a two way thing; hearing and speaking. From my view, communication with God (prayer) isn't done in the right manner as most Christians only pray when they are in need of a thing neglecting thanksgiving and hearing from God. Waking up daily is a daily miracle that demands thanks given to God. Most times when hearing from God is being talked about people expect to here a loud voice speaking to them from the sky not knowing God's word is all around us in the form of the Bible and his servants to earth (pastors etc).
Most times what we get bothered about is already sorted out by God but we don't know and can't tell how to go about it because we don't have a good relationship with the Father.
We should learn to pay more attention to God's word and not just demanding from God whenever we're in need..life gets easier that way.
Meditate on this bible verse daily
"Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus." Phillippians 4:6-7
