Those who believe and accept the truth when they hear it, are those who are the good ground, their hearts are softened, when they hear the word of God, but it has to be the right condition for the seed to grow!
A seed can't penetrate and fall deep into the earth unless the ground is soft, and it won't grow unless the conditions are right. Hardness, pride and reviling and such, are not the heart condition that the seed needs to grow in. A heart of humility, one who when they hear the word and take it in, and show that they are willing to repent and do the will of God, is, and God will give us the strength through Christ, to overcome!
2 chronicals 34
“Because thine heart was tender, and thou didst humble thyself before God, when thou heardest his words against this place, and against the inhabitants thereof, and humbledst thyself before me, and didst rend thy clothes, and weep before me; I have even heard*thee*also, saith the LORD.”*
And i don't mean the heart that pumps either!
