Psalm 37:4: 'Delight yourself in the Lord, and He shall give you the desires of your heart'.
'To delight' is like the 'radiance' in a baby's face upon seeing her beloved mommy & daddy approaching! I remember seeing this in my daughter Sophia's face when she was a toddler then. Pastor Sharon and I were so busy at work then that we had to arrange a babysitter for her, and at times, we could only come and fetch her every few days. Can you imagine the delight in her face upon seeing us at the doorstep? We could literally feel her heart leaping with excitement & joy! Why? Simply because she knew her mommy & daddy love her dearly & she missed us much (just as we missed her much too!). Also because she knew her mommy & daddy are good to her, & can't wait to embrace her and give her good things! She also had complete trust that her mommy & daddy would never harm her, and have only good thoughts for her!
Beloved, that's exactly how your Father in heaven sees you (His beloved son/daughter) too! He has never meant harm to you, and is (& will always be) good to you! Jeremiah 29:11-12 says it very aptly, 'for I know the thoughts that I think toward you, says the Lord, thoughts of peace and not of evil, to give you a future and a hope. You will call upon Me, and I will (& am here to) listen'.
Delighting yourself in Him is to know (& being assured) that He is good to you, all the time!
In Luke 1:41, the baby in Elizabeth's womb was also 'leaping' at the coming of Mary who would be giving birth to Jesus! You know why the babe started leaping? Because his soul was delighted at the presence of Jesus! Hallelujah! The presence of Jesus brings much delight! So, you can say 'to delight in the Lord' is 'to have pleasure in, or taking pleasure in being with Him or worshiping Him'.
The deeper meaning of 'delighting in the Lord' is found in the Hebrew word 'anag' in Psalm 37:4. This may surprise some of you, but it actually means 'to be soft or pliable before the Lord'. It also means 'to be easily shaped and flexible before the Lord', or 'the willingness or humility to be shaped by the Lord'. In other words, 'to delight in Him' is to allow yourself to be shaped by Him, to be soft or pliable before Him, and to be willing to be led by Him. Romans 8:14 says 'as many as are led by Him, these are called sons (or daughters) of God'!
It's also not wrong for people to say 'delighting in Him' is 'to sit at the feet of Jesus and enjoy His presence', by feeding on His Word, praying in the spirit, or in praise and worship. It's in His presence that you'll receive wisdom, revelation, and guidance in life, and that's how you can be 'at the right place, at the right time, doing the right thing' always!
As you delight in Him, you'll also never miss all the goodness God has for your life! You'll even be blessed beyond what your mind can think of. His ways are always higher than yours (Isaiah 55:8-9), even in giving you every 'good thing'!
So, go ahead, continue to delight yourself in Him, and just as the psalmist David has written, 'God will even give you the desires of your heart', in His ways and in His time!
