Faith

But without faith it is impossible  to please him,
for he who comes to God ,must believe that he is ,and that he is a rewarder of those who diligently seek him Hebrews 11.6
Now faith is the assurance of things hoped for,the conviction of things not 
seen .spiritual definition is now faith is the substance of things hoped for,
the evidence of things not seen Hebrews 11.1
Having faith means you conduct yourself according to God's word by
believeing that God is a rewarder of those who seek him..
