"This is just my opionion, the problems with some of the believers is they are always asking God to come to them when we should be the one to go to the Father."

That doesn't make any sense cause if you're asking God to come to you, then you are going to the Father.

"So, in other words, what you are trying to convey is what Jesus did on the cross is not good enough."

Im not saying that what jesus did on the cross isn't good enough, what Im stating is that you can ask God for anything, because that's what He expects from us. In Isaiah 43:26, God says "Put me in remembrance; let us argue together; set forth your case, that you may be proved right." God even wants us to remind Him of His promises. When God asked me to seek Him, I asked Him for a sign of proof that it was Him who was doing the asking, and He answered me. That's why I seek Him and made Him part of my life. Just because we're in the new testament, it doesn't mean that What God said in the old testament has changed. Jesus didnt come and changed the law,instead he reminded us of two; Love thy Father with all your heart and love thy neighbor as thyself.
