Jeremiah 17 : 5 This is what the Lord says: “Cursed is the one who trusts in man, who draws strength from mere flesh and whose heart turns away from the Lord. 6 That person will be like a bush in the wastelands; they will not see prosperity when it comes. They will dwell in the parched places of the desert, in a salt land where no one lives. 7 “But blessed is the one who trusts in the Lord, whose confidence is in him. 8 They will be like a tree planted by the water that sends out its roots by the stream. It does not fear when heat comes; its leaves are always green. It has no worries in a year of drought and never fails to bear fruit.” 9 The heart is deceitful above all things and beyond cure. Who can understand it? When it comes to verses like this, it is talking about my feeling about myself. That I can't trust it. When it is starts saying I am not good enough, I might not be an elect, that i need to change my life first before I come to Christ, I fell of the horse i can't get back on, or i am not a good tree all these are excuses and we are not to listen to it, but come to Jesus. That I am to trust in Jesus over my own heart Is it having a hard heart or no heart to not to want others to do the same? Can we trust our heart in the matters of others salvation? 1 Corinthians 8 : 9 But beware lest somehow this liberty of yours become a stumbling block to those who are weak. 10 For if anyone sees you who have knowledge eating in an idol’s temple, will not the conscience of him who is weak be emboldened to eat those things offered to idols? 11 And because of your knowledge shall the weak brother perish, for whom Christ died? 12 But when you thus sin against the brethren, and wound their weak conscience, you sin against Christ. 13 Therefore, if food makes my brother stumble, I will never again eat meat, lest I make my brother stumble. 1 Corinthians 9 : 19 Though I am free and belong to no one, I have made myself a slave to everyone, to win as many as possible. 20 To the Jews I became like a Jew, to win the Jews. To those under the law I became like one under the law (though I myself am not under the law), so as to win those under the law. 21 To those not having the law I became like one not having the law (though I am not free from God’s law but am under Christ’s law), so as to win those not having the law. 22 To the weak I became weak, to win the weak. I have become all things to all people so that by all possible means I might save some. 23 I do all this for the sake of the gospel, that I may share in its blessings.
