“Working together with him, we also urge you not to accept the undeserved kindness of God and miss its purpose.
For he says: ‘In an acceptable time I heard you, and in a day of salvation I helped you.’
Look! Now is the especially acceptable time. Look! Now is the day of salvation.”
~2 Corinthians 6:1,2

Serving God is not necessarily easy nor fun. While it is not burdensome, it does entail considerable effort and sacrifice. (Matt. 7:13,14; Phil. 3:12-14; 1 John 5:3)
It may be tempting to take the easy way out and leave drawing closer to God for a future time when life is more “settled” or we feel more “prepared.”
The reason God’s Day has not come is because he wants us to repent. (Rom. 2:4; 2 Pet. 3:9)
But we do not know what will happen tomorrow or a couple years down the line. (Jas. 4:13,14)
Even if we spent 80 or 90 years studying about Jehovah and Jesus, we would still have so much more to learn about them and all they have done for us. (Job 26:14)
We cannot store up time and return it to God at a later date.
If we meditate on how we can draw closer to him today, we will have fewer regrets when we finally do run out of time. (Is. 30:18; 55:6; Eph. 4:30; Jas. 4:17)
