Happy are those who obey his decrees and search for him with all their hearts (Psalm 119:2, NLT).
God wants His children to love Him with all their hearts (Luke 10:27), to worship Him with all their hearts (Psalm 103:1), to seek Him with all their hearts (Psalm 119:2), to obey Him with all of their hearts (Deuteronomy 28:1-2), to serve Him with all of their hearts (1 Chro. 28:9), and to carry out their relationship with Him with all of their hearts.
No half measures (Matthew 26:58). No lukewarmness (Revelation 3:15-16). No standing on the fence (2 Kings 17:33). No serving two masters (Matthew 6:24). No hypocrisy (Matthew 6:2-16). No pretense (Matthew 15:8-9). Nothing plastic. Real, living, heart-felt worship. For “God is a Spirit: and they that worship him must worship him in spirit and in truth” (John 4:24). This was one major complaint of God against His people Israel, again and again. Jesus, while rebuking their hypocrisy quoted the words of the prophet Isaiah to show how God detests any worship that is not with all your heart.
Ye hypocrites, well did Esaias prophesy of you, saying, This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me (Matthew 15:7-8).
This is one reason why David endeared himself to God. He was real, down to earth, and genuine in his relationship with God. Whether to worship, to praise, to sing, to dance, to give, to judge, to fight, to repent, to cry, or to fear God. Whatever David did for God was with all his heart (Ps. 130:1). And God called him a man after His heart (Acts 13:22). I urge you today to develop a heart-felt relationship with God like David, to be really fervent in the spirit and seek God with all your heart. And He will take you from glory to glory.
I intreated thy favour with my whole heart: be merciful unto me according to thy word (Psalm 119:58).
