"If you then, being evil, know how to give good gifts to your children, how much more will your heavenly Father give the Holy Spirit to those who ask Him?” Luke 11:13
Every parent wants to give their child the world. Some do it by lavishing the best they are able to provide on their young ones. Others do it by teaching hard work, relating that nothing comes easy but equipping them to be able to acquire things for themselves. There are virtually none of us who do not want our children to have it better than we did growing up.
The interesting thing about that statement is that not many of us had it bad at all. This was because our parents wanted us to have it better than they did and so it continues.
Beloved our kids do not have to ask for most of the things we provide. If they ask persistently, we are likely to relent even if we are not necessarily predisposed to give them that thing. This is analogous to our relationship with our heavenly Father. He lavishly gives so much and so constantly, we take Him and his blessings for granted yet we still take our wants and needs to Him. Let us lift our minds from the material to things such as mates, recovery of health, answers to inquiries, solutions to problems, relationships and so on. These are things that are important to us. God invites us to bring these prayers and supplications to Him.
Jesus said we should always pray and not give up (Luke 18:1). He also rhetorically asks, "Will not God bring about justice for his chosen ones, who cry out to him day and night? Will he keep putting them off? I tell you he will see that they get justice, and quickly" Luke 18:7-8. Not only does persistence pay, it is authorized and encouraged.
